Introduction to household registration card: On May 3, 1946, the CCP delegation moved from Chongqing to Nanjing. There were more than 200 staff members. They lived at Nos. 17, 30 and 35 of Meiyuan New Village respectively. In order to monitor the actions of the CCP delegation staff, the Kuomintang government registered and filed all delegation staff and their families, and established collective household registration cards and individual household registration cards. The heads of households on the household registration cards are all Zhou Enlai. The personal household registration card also contains my photo, job title, and the time of coming to Nanjing. There are currently 22 collective household registration cards and 87 individual household registration cards.
