First of all, this is determined by the diet structure of China people. People in China don't like cold food, and lunches are generally cold. Even if they are heated in the microwave oven, the taste will be greatly reduced.

Secondly, China has a vast territory and abundant resources, the catering industry is developing rapidly, the take-away service is quite perfect, and all kinds of application software for take-away service are available, so people in China don't need to bring their own lunches at all.

Finally, many units or companies have their own canteens, which can meet the dining needs of employees without lunch.
