The teaching profession in China is no joke at all. Chinese government does all it can to motivate teachers at all levels especially primary and secondary levels. Teachers at most schools get free lunches — and a good one at that. The lunch is traditional: one meat dish, two vegetable ones, some rice, and a bowl of soup. Expensive private schools also offer fruits and yogurt.
The meal is served at canteens to teachers.
This is seen as a good opportunity to enjoy a traditional Chinese lunch while chatting with colleagues.
