Another is that Tangshan only lends you files, and you can only go to Tianjin to borrow files. At this time, Tianjin talents will not give you a "letter of introduction", then your cadre status will be gone. When you return to Tangshan with the so-called secondment file, Tangshan agrees to take over your file. You can ask Tangshan to give you a certificate of acceptance and then go back to Tianjin to open a letter of introduction, so you can transfer this cadre relationship.
It was only in the north that I managed to borrow the documents and finally took them out. Then I agreed to accept them locally and not go to Tianjin to open a letter of introduction to adjust the relationship. Too much trouble. It's no use being a cadre in a state-owned enterprise these days, no matter what.
