Excuse me, where is the specific location of Changxintong? I took part in their campus recruitment, saying that they wanted me to go to the courtyard of Hepingli East Street 1 1 in Dongcheng District, Beijing! On the map, the number of Hepingli East Street 1 1 is Beijing CINODA Technology Co., Ltd. Changxintong is located on the 2nd floor, 8th floor, Datang Telecom Research Institute, No.40 Xueyuan Road, Haidian District, Beijing, and its telephone number is (010) 6230491. In some places, it was found at No.60, Hepingli East Street, Dongcheng District, Beijing. Tel: (0 10)58049224. Personally, I think the number 1 1 is more reliable. You can call first and then have a look.
