1, working hours: hospital canteens need to operate around the clock to meet the catering needs of medical staff and patients. Aunties need to start working very early in the morning and stay busy until late in the evening, and also need to work shifts or overtime.

2. Workload: In a busy hospital, the cafeteria will have a large number of diners, especially during peak meal times. This results in a high workload for the aunts as they need to handle a large number of orders and cleaning work.

3, the nature of the work: canteen work includes tasks such as preparing food, cooking, cleaning, washing utensils and serving customers. These tasks require long hours of standing, as well as repetitive physical labor that can lead to physical fatigue.

4, the working environment: hospital cafeterias can be noisy and busy, and the need to maintain efficiency and accuracy under pressure can increase psychological stress.
