Why do girls in China often buy meals with foreigners from China?

Because in many cases, it is a question of cultural differences. Foreigners are prone to make jokes when eating, and their understanding of food is not very thorough. They can only buy rice by gestures. Most of our chefs who sell rice in China are not proficient in foreign languages. Even foreigners know Chinese, but their understanding of Chinese in China is not deep enough. So in front of friends in China, friends in China usually buy rice for them and daily necessities for them.
