Xiao Yun cigarette is a local name in Fujian province, which is famous for producing fake cigarettes all over the country. Later, people used Xiao Yun cigarettes as a substitute for fake cigarettes. It is illegal to post a video of the concept of "Xiao Yun cigarette" on Tik Tok, because it is forbidden to post any form of tobacco advertisement on the platform, including but not limited to cigarettes, e-cigarettes and pipes.
Therefore, the video of "Xiao Yun cigarette" advertising in Tik Tok is probably false and unreliable.
