People in China are generally lactose intolerant, which is because lactase in China population is relatively insufficient, and lactose cannot be completely digested, thus causing discomfort. However, this does not prevent milk from being widely promoted and popularized in China.

First of all, milk is rich in nutrients, such as calcium, protein and vitamins, which play an important role in health. Especially in China, the problem of osteoporosis is becoming more and more serious. Calcium in milk is a very important nutrient, so promoting milk can help people eat more calcium and help alleviate the problem of osteoporosis.

Secondly, although people in China are generally lactose intolerant, some people can tolerate lactose in milk, and some people will not feel uncomfortable after drinking milk, which provides conditions for promoting milk. For lactose intolerant people, low lactose or lactose-free dairy products have also appeared in the market, and these products are gradually recognized by consumers in China.

Finally, milk has become an indispensable part of China's food culture, especially at breakfast, many people will choose to drink milk. Therefore, promoting milk can help people better understand the nutritional components of milk and let people better enjoy the benefits brought by milk.

To sum up, although people in China are generally lactose intolerant, the promotion and popularization of milk as an important nutritious drink is still of great significance.
