Lawyers generally practice the working system of five days' rest and two days' rest, but some people will be on duty on Saturday and Sunday and can practice. A lawyer's job is flexible. In fact, there are very few people working in the office, and there is no need to rest on Sundays. Some people are not in the office at ordinary times, such as appearing in court, taking evidence and investigating. Maybe some law firms are relatively small, and the rest time is set by themselves. Regular law firms have the same working hours as courts and procuratorial organs.
