According to the Advertising Law of People's Republic of China (PRC), advertisements should not contain false or misleading contents, and should not deceive or mislead consumers. If the word onychomycosis is stuck on the door of a pedicure shop, it will usually be considered as a false advertisement and will be subject to administrative punishment. If you need to promote your service, you can choose to promote it in the store or through other legal channels. At the same time, for the sake of consumers' health and safety, stores should also publicize their services truthfully, and must not exaggerate or mislead consumers.
