& shy; 12-year-old Xiaojie (alias) has not applied for a registered permanent residence for family reasons and has become a “black household”. Seeing that the child was about to go to junior high school, Xiao Jie’s grandmother was anxious and asked the police for help. Recently, with the help of Fuzhou Mawei police, Xiao Jie’s household registration materials were finally completed. & shy; On February this year, Grandma Cai, who lives in Qiaotou Street, Min’an village, Mawei, Fuzhou, turned to Chen Xu, a policeman from Tingjiang police station, public security bureau, Mawei district, Fuzhou city for help. It turned out that Xiao Jie, the grandson, was born to Grandma Cai’s son and his cohabiting girlfriend in Germany 12 years ago. At that time, the two did not go through the marriage formalities. “Later, the two were not together, and they married foreigners and formed a new family.” Grandma Cai said that Xiao Jie had always stayed at home and was raised by her. & shy; However, Xiao Jie was born in a German hospital and her birth certificate was lost again. Grandma Cai was the only one who could prove Xiao Jie’s credentials to return home, it was the travel permit issued by the Chinese Consulate General in Hamburg in 2006. Incomplete materials caused Xiao Jie to be unable to declare his account for a long time. & shy; After knowing the situation, Chen Xu, a community policeman, went to foreign affairs, Overseas Chinese Federation and other departments several times to consult relevant laws and regulations, and took Xiao Jie to Fujian Provincial Hospital to extract DNA samples, and mail the sample to Toronto, Canada where Xiao Jie’s father is located for paternity testing. After several twists and turns, Xiao Jie’s household registration materials were finally completed. (Reporter Wu Zhenmao Chaoqing correspondent Rong Police)
