Do it in a patent agency? How is the income?

As an agent, it is generally the basic salary plus commission, that is, if you take more jobs, you will get more points. Wages generally vary from place to place, and coastal areas are generally higher than those in the mainland. If you do a lot of work in coastal areas, you can get10-200 thousand a year. I don't live much, like 45,560 a month. Besides, doing this is very tiring and requires a high degree of concentration all day. If there is no problem in this regard, you can consider doing it.
