I don't know if it's illegal. It's the first time I was caught stuffing a small card into a hotel. Will I get caught?

It's okay. Small cards are only for advertising. If you catch it, you will only be told to go away. Usually don't delve into it. It is illegal to post small advertisements, but it is not illegal. At most, it can only be administrative detention or public security detention, and can't be sentenced.

Article 32 of the Advertising Law also stipulates that outdoor advertisements shall not be set up under any of the following circumstances:

(a) the use of traffic safety facilities, traffic signs;

(two) affect the use of municipal public facilities, traffic safety facilities and traffic signs;

(three) hinder the production or people's life, damage the appearance of the city;

(four) the construction control zone of state organs, cultural relics protection units and scenic spots;

(5) Outdoor advertisements prohibited by local people's governments at or above the county level.
