The reason why the Hui people banned smoking and alcohol was mainly influenced by Islam. Islam forbids drinking alcohol, because alcohol is harmful to people's health, there is a risk of alcoholism, and it will make people lose their minds and destroy religious activities and good-neighborly relations to a certain extent. In addition, Islam believes that tobacco is an anesthetic, and its smoke and taste are attractive, which will distract believers and violate religious principles. Therefore, Hui Muslims do not smoke and drink, and other Muslims do not recommend smoking and drinking.
