1. Polite reminder: You can walk up to the readers and politely remind them that eating is forbidden in the library and tell them that this is to maintain the quiet environment of the library and protect books.
2. Explain the regulations: If readers don't know the regulations of the library, they can explain them in detail and tell them that they may be punished if they violate the regulations again.
3. Ask the supervisor for help: If readers still don't listen to advice, they can find the supervisor of the reading room, tell them the situation and ask them to help persuade.
In a word, eating in the library is against the regulations and should be stopped and discouraged in time. At the same time, in order to maintain the order and environment of the library, it is also suggested that everyone consciously abide by the relevant regulations.
