If it is a computer, you will find a bar service announcement in the category of the boutique area, or a similar category (this is set by the bar owner himself, which is very casual) and then click on it. There will be a list of positions in this category, which should include regulations.

Or click on the search bar next to Baidu above and enter "rules" in the keyword, so that you can search for posts according to keywords and filter them inside.

Sometimes the bar rules will not be topped for some reason.
