Can those who have already applied for Zhengzhou trade union card apply for Henan trade union card again?

No, there are only union members in China.

(1) If you have already applied for a trade union card but lost it, you can't apply for it again. You need to bring your ID card to Bank of Zhengzhou to have it reissued. (2) If you have a trade union card in a foreign country, you can't do it again this time, and you can transfer to a trade union member. The specific steps are as follows: download the yugong club APP→ join and transfer →-I want to join and transfer (I need to upload the work certificate and ID photo of the current unit trade union). (3) The staff who did not apply for the trade union card must do so this time, and the staff who bought the post on their behalf volunteered to do so. The handler is equivalent to joining the membership voluntarily and paying the membership fee, which is 10 yuan per month.
