Why is sexual harassment called "eating tofu"?

"Eating tofu" is a popular word "sexual harassment" in China in recent years. Allusions 1 It is said that in the old society, tofu shops were mostly husband and wife shops. My husband gets up in grinding bean curd in the middle of the night, and my wife sells tofu during the day. The proprietress of the tofu shop treats tofu as a household food, which is naturally tender skin. At the same time, in order to attract customers, this is a coquettish move, which leads the men around her to flirt with the proprietress in the name of "eating tofu". So the jealous wives said discontentedly, "Did you eat tofu again today?" Scold her husband. In the future, "eating tofu" became synonymous with men and frivolous women. Allusions 2 Another statement is more credible: there was a habit of "eating tofu" in the old days. There must be tofu in the food prepared for bereavement, so it is called "eating tofu" or "eating tofu rice" to mourn. In the past, farmers in Jiangsu and Zhejiang held funerals at home, and some people were asked to help move a body from home to the cemetery for burial. When it's time to eat, the host will set some tables in the yard or on the open space in front of the door and bring the food to the villagers who help. But at this time, there will be some idle people sitting at the table, and no one will help to eat. Even if the owner finds out, it is not convenient to drive away. Funeral meals are relatively simple, mainly tofu, and white is the main color of funeral. Some villagers went to help, saying that they went to the funeral home to help, saying that they went to eat tofu rice. For the guy who doesn't work and eat rice, he is also said to eat tofu. This is probably the origin of the word "eating tofu". This humorous and ironic new word began to spread in Shanghai in the 1930s. It is typical and common in life that some men love to flirt with women and even take advantage of them, so they are called "eating tofu". That is, the so-called "all hands take advantage of others" in the article "Eat Tofu" is also true. Some people also say that "tofu" has four characteristics: white color, fine surface, tender quality and soft quality, which coincides with the characteristics of "young woman" with white skin and weak temperament. So "eating tofu" is used to refer to flirting with young women. ]
