How did CCCC-AIC- 1 Company sign the tripartite agreement for undergraduates?

Every year, we will recruit fresh graduates from the First Aviation Administration and a company. A tripartite agreement form will be sent to the original school. After graduation, report to the unit with a registration card, and show your diploma and degree certificate. After the unit receives it, the school will mail files, transfer the relationship between the party and the masses, register in Tianjin Development Zone, and enrich personnel to various construction project departments.
