The entry requirements of specialized agents are relatively high, especially in big cities like Beijing and Shanghai. Moreover, the talent training mechanism in this industry is basically the traditional one-on-one apprenticeship system of "master with apprentice". In the first few years, I worked as a master's assistant, that is, doing odd jobs such as sending and receiving documents. It takes two or three years to learn the real skills. If you really want to be a patent agent, you might as well attend the vocational training for patent agents. That would be nice.
