You can sit down now. In China, waiters generally need to stand to serve guests, but there is no clear rule that waiters can't sit down. Therefore, waiters can sit down and have a rest during work breaks or when they need to have a rest, but they need to pay attention not to take too long breaks, so as not to affect work efficiency and service quality. In addition, different restaurants and service places have different attitudes towards waiters sitting down. Some restaurants will require waiters to stand all the time, while others will provide waiters with rest areas and chairs. So you can sit down as a waiter in Shanghai.
