The pinyin for cengfà n

expansion: cengfa is an act of contacting strangers through social networks or other channels, taking advantage of the hospitality of strangers and enjoying free meals at home. In China, the phenomenon of eating rice became popular in the 2111s. With the popularity of the Internet, this kind of behavior gradually became open and large-scale.

In recent years, Ceng Fan has become a popular theme of variety shows, such as Dear, Come for Dinner and Show for Dinner. These programs show the real relationship and daily life of different groups of people through the meeting, understanding and interaction between stars and amateurs, and also express people's yearning for love, sharing and friendship. However, some critics think that it is an immoral behavior and violates public morality and etiquette. They think that it is a "black" act of mutual assistance to interfere with strangers' family life in exchange for their short enjoyment, which will disrupt social order and endanger social morality.
