Chinese immigrants booked their passages on ships with the Pacific Mail Steamship Company (founded in 1848) and the Occidental and Oriental Steamship Company (founded 1874). The money to fund their journey was mostly borrowed from relatives, district associations or commercial lenders. In addition, American employers of Chinese laborers sent hiring agencies to China to pay for the Pacific voyage of those who were unable to borrow money. This "credit-ticket system" meant that the money advanced by the agencies to cover the cost of the passage was to be paid back by wages earned by the laborers later during their time in the U.S. The credit-ticket system had long been used by indentured migrants from South China who left to work in what Chinese called Nanyang (South Seas), the region to the south of China that included the Philippines, the former Dutch East Indies, the Malay Peninsula, and Borneo, Thailand, Indochina, and Burma. The Chinese who left for Australia also used the credit-ticket system.
