During the Song, Yuan and Ming Dynasties, the city shipping companies were established in Guangzhou and Quanzhou. After the Qing government announced the opening of the maritime ban, in the 23rd to 24th year of Kangxi (1684-1685), it was named "Customs" for the first time, and four customs offices were set up in Guangdong (Guangzhou), Fujian (Fuzhou), Zhejiang (Ningbo) and Jiangsu (Shanghai).
