I am a foreigner, and I came to Zhuzhou for some reasons, and I want to find some odd jobs to support myself. Can anyone recommend a place to go?

It is really good to have some skills at hand, but only if you have a direction of interest, especially during your apprenticeship. Interest is not only the reason for your persistence, but also the motivation for your efforts. I suggest that if you have no direction, spend a year or so doing odd jobs in all walks of life to see what you are suitable for. There is a local part-time exchange place in Zhuzhou, and you can also find a job online. Just send me a private message.
