Where can I find the information of summer recruitment in Yinchuan?

You can go to the job fair on weekends. Last Saturday, I went to the job fair and met several companies that are recruiting summer jobs. But it's usually a promotion or something.

Also, how can you say that there is no part-time job information on the recruitment website?

/Above this, in the lower right corner of the webpage, are all part-time job information. Go up and look for it.
