Hunan people like to chew betel nut, which is not only popular, but a custom with a history of hundreds of years. It is said that during the Shunzhi period of the Qing Dynasty, a plague prevailed in Hunan and many people died. But those Hainan businessmen who like to chew betel nuts are safe and sound. As a result, Hunan people began to learn to chew betel nuts, which was out of control.

Nowadays, Hunan people have to socialize, visit relatives and friends, and celebrate the holidays.

Chewing betel nut is harmful to some extent. People who like to chew betel nuts have dark teeth and red mouths. Especially people who chew betel nut for a long time are prone to oral ulcers, and some people get oral cancer because of chewing betel nut.

In 20 17, when China Food and Drug Administration published the list of carcinogens, betel nut was classified as a first-class carcinogen.
