I can't answer this question directly because I have no personal experience. But generally speaking, Nanjing hotel work may include tasks such as reception at the front desk, room cleaning and restaurant service. The nature and difficulty of each job are different, but each job has its own unique challenges and requirements. Working in a hotel usually requires busy work intensity and high standard of customer service, which may require certain skills and endurance. Besides, everyone's experience of work will be different. Some people may feel that the work is hard, while others may feel relaxed. So it depends on your own physical strength, mentality and work experience.
