In the cold winter, many car owners will struggle with whether the air conditioner in the car should use internal circulation or external circulation. For this problem, people who don't understand cars may choose at will, but people who understand cars analyze it and realize that they have been doing it wrong before.
First of all, we need to understand the basic concepts of inner circulation and outer circulation. The internal circulation refers to the circulation of air in the car driven by the air conditioning system, while the external circulation is to introduce fresh air from the outside into the car and exhaust the air from the car at the same time.
In winter, most people may prefer to use the inner cycle, as it allows the temperature inside the car to be more stable. However, prolonged use of internal circulation can lead to poor air quality in the car, increased carbon dioxide concentrations, and even possible hypoxia. In addition, if the outside air is too foul or there are harmful substances, the use of the internal circulation may cause health effects.
In contrast, the external circulation can bring in fresh air, keeping the air inside the car fresh and clean. In the case of good outside air quality, the use of external circulation can not only improve the comfort of the driver and passengers, but also help to improve the air quality in the car.
Of course, in some cases, we still need to use an inner loop. For example, in smog days or when the vehicle is driving on the highway, in order to prevent the external dirty air from entering the car, we should turn on the internal circulation in a timely manner.
To sum up, when using the air conditioner in the car in winter, we should flexibly choose the internal circulation and external circulation according to the actual situation. While ensuring the right temperature in the car, it is also necessary to pay attention to maintaining the freshness and cleanliness of the air in the car. This not only improves the comfort of the occupants but also helps to protect our health.
Cao Dewang: Don't be stupid, the rich have several houses, and only the rich will sell to the rich in the future
Cao Dewang, a well-known entrepreneur in China, is known for his unique business vision and profound social insight. In a recent public speech, he made a thought-provoking point about the current state of China's real estate market: "Don't be stupid anymore, rich people have several houses, and in the future, rich people will sell to rich people." Although this sentence is short, it reveals the future development trend of China's real estate market, and also provides a warning to the investment strategy of ordinary people.
First, Cao's remarks reveal a striking feature of China's real estate market: the wealthy own multiple properties. This is both an economic phenomenon and a social problem. From an economic point of view, with the development of China's economy and the increase of people's income, more and more wealthy people have appeared, and they have enough financial resources to buy multiple properties. At the same time, China's real estate policies have also prompted some wealthy people to buy multiple properties as an investment. However, this approach to investment also brings social problems. On the one hand, the emergence of multiple properties has exacerbated the imbalance between supply and demand in the real estate market and pushed up housing prices, and on the other hand, this investment method has also exacerbated the social divide between the rich and the poor, which is not conducive to social equity and stability.
Second, Cao's remarks foreshadow a future trend in China's real estate market: property transactions between the wealthy will become mainstream. Over time, property for the affluent will become a major source of supply in the market. And because the wealthy have similar economic strength and investment philosophies, their property deals are easier to conclude. In addition, with the development of China's economy and the aging of the population, some wealthy people may choose to transfer their properties to other wealthy people to realize or pass on their assets. As a result, the real estate market in the future will be more inclined to trade between the wealthy.
For ordinary people, Cao's remarks remind us that we need to pay attention to changes in the real estate market and adjust our investment strategies. On the one hand, we should not blindly follow the trend to buy multiple properties, so as not to cause economic burden and investment risks, on the other hand, we also need to pay attention to the changes in the real estate market, understand the investment trends and trends of the wealthy, so as to formulate a more scientific and reasonable investment plan. At the same time, we also need to maintain a rational and calm investment mentality, not be confused by short-term fluctuations in the market, and adhere to the concept of long-term value investment.
In conclusion, Cao's remarks reveal the current situation and future trends of China's real estate market. We need to seriously think about and respond to changes in the market, and formulate a scientific and reasonable investment strategy. At the same time, we should also pay attention to social fairness and stability, and promote the healthy development of the real estate market. Only in this way can we achieve long-term growth in personal wealth and sustainable socio-economic development.
