On June,1927, the Travel service Department started to manage affairs on its own, hanging up the big signboard China Travel Service. Later, the name "travel service" was adopted by many people of the same trade, and is still in use now. After the Travel Service Department changed its name, Zhu Chengzhang, now the first Director of the China Travel Service, lost no time in concluding agreements for mutual aid and cooperation with a few foreign travel agencies of international renown. Travelers who had letters of introduction from the China Travel Service was, therefore, able to move beyond China's borders and extend its services to many parts of the world. Its branch offices, which had been expanded to more than 40, were distributed over China's various big cities and famous scenic spots. Hong Kong and Singapore also had its branches, and Shanghai boasted ten.

The scope of business also expanded to cover the following: selling air tickets, issuing and cashing traveler's checks, strengthening the reception of foreign travelers, booking hotels in towns or cities other than Shanghai, handling the consignment of baggage and goods for shipment, acting as insurance agent, and rendering postal and telecommunications service.
