Is it really promising to do part-time translation or interpretation at home?

Free translation with clear direction, solid professionalism and rich experience is promising.

The unit price difference between entry-level interpretation and advanced interpretation is not as high as translation. The difference lies in what kind of projects you can receive.

If you don't have any translation experience, basically only the general life escort or exhibition (short-term) translator will come to you, and the probability is extremely small, because this is a job that an ordinary English college student can do. Just contact the English college in the university directly to arrange it, because students have more time. The unit price of this kind of project is not high, and you have to spend a lot of energy to ensure that you can find a job every day for a month (which is impossible).

If you have accumulated some experience in interpretation projects, you can consider undertaking long-term (more than one month) projects. Most of these projects are on-site escort projects, usually accompanied by engineers in factory workshops and engineering sites. The unit price is not much higher than the basic project, but generally you will include accommodation (although this is not income, you have to spend it without it), and at the same time you can have a relatively stable income compared with short-term projects, so you don't have to spend it all the time.
