You don't need to bring your own lunch box. There are rice cookers and chopsticks in the school canteen. Just take them to the designated place after eating. If you want to go back to the dormitory to eat, you should bring your own. The meal card will be sent to you when you report for duty, so keep it well, because it is thin and fragile ... the meal card is used for bathing and fetching water at school. When I give it to you, you can use it directly in the canteen and Lihu restaurant.
