Founded in Shanghai in 1921, the firm also had operations in Hong Kong (established in 1937). Wu Zhifan became CEO of Tien Chu Ve-Tsin. Following the establishment of the People's Republic of China, Tien Chu Ve-Tsin became a state owned enterprise. It is currently owned by Shanghai Industrial Holdings. The Hong Kong unit became Tien Chu Ve-Tsin Chemical Limited of Hong Kong in the 1950s, but it reunited with the mainland  parent firm in 1981. The factory was located in Tokwawan, Kowloon.
