Hong Chengcheng is the female guest number two in "Heartbeat Signal 4".
Because the show has received a lot of attention from a large number of viewers, it has attracted a lot of attention.

Hong Chengcheng's introduction in the program is a doctoral student at Harbin Institute of Technology (Shenzhen), majoring in medical data science.
From the beginning, everyone thought that he was a bully, and everyone also thought that Hong Chengcheng would be a full-fledged female doctor after that.
Unexpectedly, after two months, the news of Hong Chengcheng's withdrawal from school spread.
She herself responded to this in the comments section, saying that she had indeed dropped out of school and could not be a female doctor, but she could work happily with the straw bale.
This straw bag is a very modest statement, even if she is not a female doctor, she is also a female master.
Such a degree is also the highest in reality, the highest degree is a graduate student, and graduate students are divided into two directions.
Doctoral and master's students, Hong Chengcheng is still a master's degree, and the ph.D. is only a different research direction.
It's just that there is still a big difference between a doctorate and a master's degree, and a doctor can always win a higher reputation and admiration.
What's more, Hong Chengcheng is not the female doctor that everyone imagines, and many alumni have stood up and said that the number of times she went to the laboratory during the school period was not much, and she did not feel like a scientific researcher.
It is also said that she was dropped out of school and saw her in the elevator room begging her mentor to let her participate in the group.
This behind-the-scenes report has lowered Hong Chengcheng's image as a bully in everyone's mind.
I thought she was a very smart girl with a very high IQ, the university was 985, the master's degree was overseas, and the doctoral student was also studying at Hitachi University of Technology.
I didn't expect to be dissuaded.
Everyone also knows that the doctorate is a high achievement for many people, and obtaining a doctorate is not only a test for yourself, but also the people around you will be awe-inspiring after listening to it.
And this title will also get a certain income, to a certain extent, representing high-income people.
Because participating in the show, the people in the show or various factors affect Hong Chengcheng, so that she did not become a female doctor, is this really worth it?
According to the news, Hong Chengcheng also began to carry out a certain amount of goods, and some merchants found her to talk about cooperation.
In this way, he is also half a public figure and has become a small Internet celebrity.
Is it a higher income to be an influencer, or a doctor?
For the sake of the show, because of fame, or because of Ma Zijia and Xiaokong in the show, he lost the opportunity to get the title of female doctor, is it really worth it now?
There is a saying on the Internet that I particularly agree with, doctoral graduation is not a matter of making money, but a question of how much money you make.
In "90 Marriage Agency", there are also female guests A Zi, who is also a 26-year-old female doctor, and she herself publicly said in the program that she has not yet graduated, and the annual salary is about 500,000.
If the PhD student graduates, the income should be able to increase a little more.
Assuming that Ah Zi, who is also a doctoral student, has an annual income of 1 million yuan after graduation, then it is predicted that Hong Chengcheng will also be at this level after graduation.
Referring to the same about 28-year-old female doctoral salary of 900,000 yuan a year, if you sell courses online, do video, doctoral graduation is still very convincing.
Work harder, earn 1 million a year or within the scope of ability.
After all, the people who can read the doctorate are already very unusual, and they are good at eating.
Then the income of internet celebrities must be at least more than one million, so that they can pull back a round in income.
As for achievements, this is difficult to surpass.
Do you think it is worth It for Hong Chengcheng to give up female doctors and become female Internet celebrities?
