There is no way to estimate the specific income. Because cities, systems and law firms are so different. I can only tell you the general situation of Beijing, so I won't tell you the public security law. You can probably guess the specific situation. General paralegals and trainee lawyers range from 800-3000 in small offices to at least 2000 in large ones. If there is a case source to take commission, the income elasticity will be greater. It's basically difficult to get into college, because the requirements are very high, such as foreign languages, professional knowledge, interpersonal relationships, work experience ... It's definitely not your call.
Other underdeveloped areas will be better off because of the shortage of talents. But it also depends on your own business ability, but there is less competition.
The general counsel of large enterprises employ famous barristers, and those who have just been admitted are assistants, who are said to be secretaries and chores. Even small enterprises are willing to use people who have just passed the judicial examination as legal advisers, because their own enterprises are small in scale and there are not many jobs. So the salary won't be too much.
The development prospect of this industry, I can only say, support to death, starve to death. For example, I once met a barrister, who was an intellectual property agent of a multinational company. He was an infringement in montague for one year. Guess what his income is? I also met a female lawyer who represented criminal cases. She said that her income is not as good as that of ordinary company employees. Sometimes she doesn't have a case source for months, and some people still don't give her agency fees. Sometimes all they do is lose money to others.
This has much to do with personal ability, interpersonal relationship and opportunity.
I can only tell you the general situation, which is basically what I have contacted. The situation in many cities is different. I don't know much about it. I can only tell you what I know.
You are going to engage in this industry, please think twice.
