1) hospital
Hospitals are as busy as vegetable markets, especially since the outbreak of the epidemic, people pay more attention to personal health.
Many people save money and spend it on seeing a doctor after retirement. Medical treatment, selling medicine is really meager profit.
2) Education
Education is the foundation of national development, without which it is impossible. As the most populous country in the world, China also has the largest number of students in the world. The education mentioned here is not nine-year compulsory education, but so-called training courses. Classes that don't know how to get to the training class, classes that want to learn interest, adult learning, self-study and textual research are all training classes, and the fees are not cheap. From 1 000 to several hundred, from 10 to 20000, especially the upsurge of online courses in recent years, a set of courses is likely to save millions.
3) Tobacco
It is said that smoking every day is harmful to health, but tobacco is sold out every day. In China, the tax paid by the tobacco industry is still extremely high. Now cigarettes, a pack of dozens of dollars, are just cigarettes, a car full of cigarettes? You can make as many cigarettes as you have money, and the profit here is dozens of times.
4) Lottery tickets
As China has a large population and a large base, many people buy lottery tickets. The income of the lottery industry is only a few. Every lottery unit building is the same as the White House.
