How much is the ticket for the job fair in Changchun International Convention and Exhibition Center?

Generally, it's 20, but sometimes students can win by acting as an agent in the school, 15 ~ ~ Try to see if there are any students' schools with agent tickets ~

I bought 15 RMB that year. There were too many people when I went in, but I didn't check in. I sold it at the ticket office 15 when I came out ~ ~ (* _ *) hee hee. ...
