All university libraries can enter as long as there is no access control system. If you have access control, you may not be able to get in because there is no key card, but you can study in the classroom. You can't rent a meal card If I rent it to you, how will people eat? But there are windows in the university, and you can buy food without a meal card. Just pay. It is said that the food in Liaoning University is good and the price is not high.
