Legal analysis: It is definitely illegal to post small advertisements on telephone poles, because according to relevant national laws and regulations, we are not allowed to post advertisements on power facilities. For example, it is illegal to climb poles or towers of overhead power lines without authorization, or to paste advertisements and hang billboards on these devices. This kind of behavior is not only illegal, but also particularly unsafe. After all, these are all electrical equipment, and there are great security risks. If there is an accident, it will be a pity.

Legal basis: Article 50 of the Regulations on the Administration of City Appearance and Environmental Sanitation depicts, scribbles or posts on trees, ground, buildings, structures or other facilities, and shall be fined between 100 yuan and 500 yuan; If it is not cleared within the time limit, it will be cleared on its behalf, and the expenses required will be borne by the violator.
