(Text: Seongnam Grass and Trees)
Idle for many, many days, in fact, every day I want to write something, look at Weibo and the circle of friends, put down the mobile phone and computer, choking uncomfortable, do not know what to say and where to start.
In the past two days, I have seen many people return to work, and my friends around me are still staying at home, watching the news crowded with people is very nervous, and there will be an optimistic illusion that normal life order should be restored. Not yet, look at the daily diagnosis data, don't beat yourself up, bear with it.
For more than half a month, I went to bed at four or five o'clock every day, woke up my mobile phone full of dozens of pushes, and had unexpected new messages every day. This article also dragged its feet for two days, and if I can't finish writing, I'm afraid there will be some changes, and today I will make a break.
It often feels like you can't see your head on a day like this. It's only been less than twenty days.
The twenty-ninth year of the year from Beijing back to Tianjin home, originally and parents happy New Year, the result of the outbreak of the new crown, even supermarkets and vegetable markets dare not go, until now a total of downstairs to take three times takeaway food, Tianjin also began early closed management, the old feel that they are in the school, walk to the door registration office is a little nervous, only to see the takeaway big brother crossed waist dashing smoking. I don't know how my friends who are quarantined in Wuhan are doing, whether they are also isolated.
The memories of Wuhan are very good, there are beer shops that can sit down and drink a cup of wine just after eating a stomach, Wuhan University that can't walk to the end, carbon water big breakfast that can't be eaten, East Lake without mermaids, people who fall in love, people who don't talk, people who are drunk, all free and loose. Looking back now, I don't know when it will be able to restore the way it looked like in the photo.
Photo taken in November 2016
I don't know what tomorrow will be, whether it will get better, what spring will come or something, of course, come, Zhou Huajian did not say, come and go.
I remain pessimistic and protect myself, and I hope that everyone will protect themselves as well.
Wanting to do something practical, I wrote this six-thousand-word article. Including pumping, popular science, life experience.
<h1 class="pgc-h-arrow-right">01</h1>
<h1 class= "pgc-h-arrow-right" > can be defended, can endure to endure </h1>
For me, in addition to buying vegetables and throwing away garbage, it is not difficult not to go out, as long as there are three conditions: social fear, there are cats, and hoarding food.
But I also understand that lively friends who like to go out, why it seems that standing downstairs to breathe fresh air is wrong, taking an elevator is life-threatening, half a month ago was not like this.
There is no accurate news of the inflection point and platform period at present, and I feel that I am getting closer and closer to me and my friends around me, but one thing has been repeated for a long time, and everyone will gradually slack off and let down their vigilance, feeling that this matter is not their turn. At this time, I can only endure.
A while ago, I also dared to call pancakes and fruits to take out, but now I don't dare to buy a dish and go home to wipe the bald skin with alcohol. Now I can bear it, I don't eat it.
Things get bad all started with luck.
This year, Tianjin's epidemic handling speed and information disclosure have been praised, the awareness of relatives and friends in the family is surprisingly high, and my aunt, who was once a warm and cheerful retired teacher, is so to her own daughter, I feel that my mother may not be able to do so great.
It is not easy for every friend who squats at home, after the aerosol (aerosol) transmission is certified, now it is not only frequent washing and ventilation, but also going downstairs to take out the garbage and even taking a big breath.
Douyin @ General Surgery Doctor Zeng also did a lot of popular science videos, speaking of the key and very clear, you can go to see, he is also updating the new crown related content at a high frequency.
Among the suggestions of all experts, the summary is to pull the level of protection to the highest level as much as possible, and even a professional recommends wearing a mask to sleep, feeling that he is serious.
In the current situation of high shortage of family protective materials, I feel that I can do my best and use what I can. Under the existing conditions, the highest level of protection, other fate, do not be afraid, afraid is useless. (Feel like you may not be able to do any psychological intervention-related work)
I also want to go to the gym, brought home the newly bought sweatpants and sports socks, now I can't use it, the coaches changed to online live broadcast, I pull the elastic rope every day at home. Hopefully we'll see each other beautifully and generously in March.
Everything that I don't usually care about becomes precious.
<h1 class="pgc-h-arrow-right">02</h1>
<h1 class="pgc-h-arrow-right" > stock up on some emergency necessities</h1>
Probably after this time, many people may develop the habit of hoarding goods, for example, I occasionally worry that the cream is not as valuable as the flour overnight.
Everyone has a different definition of necessities, seriously think about it, for me, shampoo, tampons, creams, body lotion, cat food, cat litter, garbage bags, laundry detergent, toothpaste, vitamins, disinfectant, wet toilet paper, masks, wine, all shelf life is long enough and really can be used and not so occupied can be called necessities, see cheap to buy some, anyway, always can be used up within the shelf life.
It may be genetic, my whole family is a hamster, and my mother will always fill the refrigerator at home without leaving a gap. Recently, when hoarding necessities, I also observed the hot search products of the supermarket near my home, and found that in the purchase evaluation, I can see what everyone has ordered, perhaps Tianjin citizens are relatively emotionally stable, and wine has not been on the hot search.
The n95 mask at home is too hard to buy more than 17 years of smog, the whole family feels that they are not holding their breath and do not love it, turn over the purchase record, two pieces of five one, inventory three people's daily activities are just enough.
Disinfectant and alcohol are often available at home, my mother loves to wipe things on the floor, I am because of the total encounter with flowers and have stayed in Cambodian health conditions are not very friendly hotel fell into the psychological shadow, go out to live with disinfectant spray, spray toilet spray hand basin spray sheet spray sofa.
A week before the Spring Festival, I felt that the situation was not quite right, and bought a few more bottles of disinfectant for my mother, found a store that could also be shipped to buy disposable masks and alcohol, four or five hours after placing an order, the big e-commerce platform was out of stock, and Pinduoduo and Hungry Mo sent drugs were also out of stock.
Call and tell your family to go to less crowded places and wear masks to go out. At that time, I felt that I was not overreacting and pushing too hard, but looking back, if the cost of this force is not high, it is no big trouble to work hard, anyway, disinfectant and masks always have a chance to be used, and the safety of the family is the most important. I didn't expect it to be a luxury now.
If you don't have the habit of hoarding things or even hate it very much, pay more attention to some news during special periods, even if the information is not comprehensive, it is not difficult to find, it may be time to do something.
You never know when you won't be able to go home, and you'll never know how many days you'll be able to stay home.
I would also like to give special thanks to the double eleven double twelve Li Jiaqi what is worth buying, is the above several efficient to promote my hoarding.
By the way, if you have a first aid kit at home, it is better, if you can't buy it now, it is okay to prepare one later, and it is better to assemble one yourself.
<h1 class="pgc-h-arrow-right">03</h1>
<h1 class="pgc-h-arrow-right" > alcohol and disinfectant are not available, you can also have these alternatives </h1>
Plug in the mask. What is worth buying has a very good topic, friends with emergency material needs can pay attention to it at any time, including real-time news, replenishment monitoring, local supply, users who are worth buying are very strict, under their eyes are not easy to make mistakes, before placing an order also look at the comments, some can pay but the delivery to March.
There is also a funny-looking protective tool at home, which I bought a few years ago for stir-frying, and later turned into a mask for shoveling cat litter.
Although I have not taken out the door yet, I think the mask + mask is not too much to go out, at least than the set of plastic buckets and plastic bags to go out can be accepted, wearing it is quite cute, Taobao search anti-splash mask can be found.
Moss, the fifth episode of the first season of "IT Madman", was also brought with him to eat oranges.
Back to the point, how to do a good job of disinfection under limited conditions is one of our recent difficult tasks. Although many people have written about the choice of disinfectant, eighty percent of them are wrong, so it is better to find out for yourself.
The original text of the "Diagnosis and Treatment Plan for Pneumonia Infected by Novel Coronavirus (Trial Fourth Edition)" issued by the National Health and Construction Commission: The virus is sensitive to heat, 30 minutes at 56 °C, ether, 75% ethanol, chlorine-containing disinfectants, peracetic acid and chloroform and other lipid solvents can effectively inactivate the virus, and chlorhexidine cannot effectively inactivate the virus.
In this picture is some disinfection and deodorization and sterilization sprays that were often prepared at home, and I originally wanted to talk about it, but I was out of stock early. Let's talk about how to disinfect the safest place in the case of limited conditions. In the picture, Kenzhisu and domol are the disinfection products I use the most, the product line is very detailed according to different uses, let's not say, the following says some can be bought.
Physical disinfection: heating, ultraviolet rays
Physical disinfection is a good means to try: hanging ironing machine, ultraviolet disinfection machine, dryer or washing machine with drying function to physically disinfect clothes and tableware.
In addition, before seeing someone half-jokingly say that drinking hot water and taking hot baths was debunked by @general surgery doctor Zeng, normal people can not live for 56 degrees of effective temperature and 30 minutes of effective time.
Medical alcohol: 75% ethanol
Ether, which has a special pungent odor, is highly volatile and toxic. According to the Regulations on the Safety Management of Hazardous Chemicals and the Regulations on the Administration of Precursor Chemicals, they are controlled by the public security departments. You can exclude it first.
Ethanol, which exerts maximum effect at 70%-75% concentrations. It is the best disinfectant at present, and everyone knows this. At present, my family relies on these two bottles, the left side is pure 75% alcohol, the right side is the compound alcohol disinfectant, the normal period is easier to buy the two.
Ethanol is relatively safe in addition to not playing with fire when using, no residue, no irritation, in addition to making the skin a little dry is no big problem.
The main ingredient of a common disinfectant gel is also ethanol, and once a small bottle of drip was cut off after a security check at the capital airport, and the alcohol content of about 60% made it impossible to carry on board.
75% two-pot head, 75% isopropanol: alternative to medical alcohol
If you can't buy medical alcohol, there are some alternative remedies:
Search for 75 degrees of wine (wine can be replaced by liquor or two pot head) this series of keywords, two pot head vodka what wine can do, just looked at almost twenty or thirty dollars a liter, cheaper than the current medical alcohol price, can not finish leaving stir-fried vegetables to drink, the following picture is casually searched Yimeng Mountain vodka.
The water of life that everyone first thinks of, 96 degrees, needs to be mixed according to the instructions below. The search found that the owners of the liquor store were particularly conscious of turning themselves into protective equipment. This wine had not been drunk, fearing that it would break me while I was drunk.
I also saw that someone recommended more than 60% alcohol content of flower dew, you do not feel too choking, it is not impossible, buy when optimistic about the instructions, if it is 30-40% do not plan.
@Mrs. Science shared a way to replace alcohol with 75% isopropyl alcoho, you can buy isopropyl alcohol can try, many disinfectant cotton tablets and wipes are effective doses of isopropanol, with sufficient disinfection effect.
84 disinfectant: chlorine-containing disinfectant
Disinfectants that are soluble in water and produce hypochlorous acid are collectively referred to as chlorine-containing disinfectants. The most common chlorine-containing disinfectant is 84 disinfectant, which was named after it in 1984. Can not buy can also be replaced by clothing bleach, the main ingredient is sodium hypochlorite, good quality and low price, but the need to pay attention to the problem is also a bit more:
1, and alcohol, in the best concentration in order to play the corresponding effect, blending ratio see the use of different manufacturers instructions.
2. Not suitable for families with pets.
3. In the process of use, the window should be opened for ventilation.
4. Corrosive to metals.
5, wipe the floor or wipe the surface of the object, 30 minutes to achieve the effect, and then wipe it with water.
6. Cannot be used with toilet cleaners. The hydrochloric acid in toilet cleaners and sodium hypochlorite 84 produce the toxic gas chlorine gas, which can kill people.
I like to use disinfectant effervescent tablets are also chlorine disinfectants, and the active ingredient of the bottle of Kenzhisu that is being used is trichloroisocyanuric acid, which has also been mentioned in the previous article. Low price, easy to carry, and the descaling effect is excellent, it is very convenient to deal with hotel bathtubs and kettles, and can also be diluted into disinfectant water, used as a spray, and the effect of 84 disinfectant is equivalent. You can still buy it just now.
But at the same time, there is another more advanced and safer disinfection tablet on the market, the active ingredient is chlorine dioxide, of course, it is better to buy this, and it is completely possible to eliminate the above bottle.
Peroxide disinfectant (safest)
It contains peracetic acid, hydrogen peroxide, peroxyglutaric acid, ozone, chlorine dioxide, potassium persulfate compound salt disinfectant, etc. Most of the disinfectants under this category are more efficient and safer, low toxicity and low irritation.
Chlorine dioxide effervescent tablets, the main ingredient is chlorine dioxide, which is completely different from chlorine-containing disinfectants, and almost no organic halogens such as chloroform are formed in the disinfection of drinking water, which is a relatively safe new disinfection product.
Weike, the main ingredient is potassium persulfate compound salt, which is originally a very safe low-toxic and high-efficiency disinfection product for pets and children's families. The results of the experiment published by the laboratory of the Hong Kong Department of Health showed that the 1% disinfectant of Econex had a killing rate of more than 99.9% of the SARS coronavirus within 5 minutes.
However, searching for relevant information, I completely lost patience.
At the end of the article, there is an article "DuPont? Or Wei Ke? " article, with a link, the author wrote very clearly. The United States DuPont company split its Chemours company to produce Weike (Virkon) series products, in 2016 Chemours sold Weike to the German LANXESS company, after 2016 the production of Wei ke has not been surnamed DuPont to change the surname lanxess, China Suzhou a company preemptively registered DuPont Weike these four big words and produced exactly the same look of the goods, and the United States DuPont and LANXESS has nothing to do with. As for whether it is valid, I will not judge it, nor will I buy it.
The main LANXESS company posted a directory of its own sellers in China, with a reference link (at the end of the article). The e-commerce platform can see the mixture of fish and dragons that can not be started.
If you've already seen it very badly, you can choose to give up with me, and low-priced and safe chlorine dioxide effervescent tablets are also a good choice.
Jing'an: Quaternary ammonium salt disinfectant (?) ）
Drip: Phenolic disinfectant (?) ）
The question mark is questionable about the effectiveness of these two types of resistance against the novel coronavirus. But because too many people are using it at home, let's talk about it.
Quaternary ammonium disinfectant: recently bought is a few bottles of net security disinfectant, at that time there was no special study on disinfection efficiency, sterilization and disinfection silly indistinguishable, the active ingredient marked above is called alkyl dimethylbenzyl ammonium chloride, which belongs to the single-chain quaternary ammonium salt disinfectant. It is possible to wash clothes and clean small wounds. Overseas versions of Drip Dew also use this ingredient.
Phenolic disinfectants: Usually the drip, Velux, Blue Moon, etc. that we buy in most supermarkets and e-commerce platforms belong to phenolic disinfectants, and the active ingredient is chlorine-resorcinol (PCMX).
If your parents are also loyal fans of Shanghai medicinal soap, although it was jointly developed by Shanghai University of Traditional Chinese Medicine, the copywriting was covered with Chinese medicine ingredients, and the cresol indicated on the packaging proved that it was also an authentic phenol disinfection product. Doubting whether it has actual sterilization effects for many years, three bows today. But as a phenolic disinfectant, it also cannot be proved to be effective against the new crown.
By the way, I thought of the legendary story of the people's old friend ShuanghuangLianrong oral liquid fighting against the new coronavirus. Remember the creator of that legendary story, the Shanghai Institute of Materia Medica of the Chinese Academy of Sciences.
Single-chain quaternary ammonium disinfectants and phenolic disinfectants, in all the data I have seen so far, for the new coronavirus, either indicate that the effect is extremely low or ineffective. If you have it at home, you can use it to disinfect clothing and surfaces on a daily basis. If there is really nothing else at home, it is also used according to the normal dose of rational optimism.
At last:
1, do not mix the use of disinfectant, you do not know what new chemicals they will produce, very dangerous
2. Choose different disinfection methods according to the application scenario
3. Under the condition of conditions, the disinfectant is recommended to be used in rotation to prevent the virus from developing drug resistance and comprehensively kill microorganisms
4. Before disinfection, be sure to clean the environment
5, wash hands frequently, ventilate more, and more people do not join in the fun
After making a rough sheet, I will write another article according to different brands of different ingredients and different uses of disinfectants, and then I can buy them again.
<h1 class="pgc-h-arrow-right">04</h1>
<h1 class="pgc-h-arrow-right" > keep moving</h1>
The other thing to say is to maintain the habit of exercising moderately and make your muscles stronger.
Can't go to the gym, lately prefer the stretch band. Specific training methods, keep, b station, little red book can be found, but also need to identify themselves, some bloggers are very fierce but the actions are wrong.
With the keep practice is also OK, I collected the following two pictures of the course, search for elastic bands, HIIT can be, is too lazy single action can play a five-minute card every day, curl, flat support, hip bridge, time can see the change. Paid courses are more chicken ribs, free is almost enough, do not blindly consume. These two screenshots are some of my favorite training programs, which are not necessarily suitable for everyone.
Many coaches are carrying out live broadcast activities on Douyin and a live broadcast, as a user, I also appreciate the curtains of the coaches' homes, pets and even old fathers, super orangutans, whether it is coach performance or operation level, I think this special Spring Festival file is the first place this year, watching their live broadcast live, I think it is a little New Year atmosphere.
When I'm done writing, I think of the lyrics these days: "You said it would have happened tomorrow." To everyone who sees it.
