To find an electrician, go to 58.com, which is the largest recruitment platform. Wherever you want to find a job, just go to Baidu and search for “58 local recruitment there”, such as: Beijing 58 local recruitment.
You can also go to popular local forums or post bars to post for help. The chances of finding one in this way are relatively high, but it’s hard to say whether you can find a better electrician. It is best to find an introduction from an acquaintance, which is also more reliable.
