was a Chinese organization that attempted to stop the tongs, but eventually collapsed when the Chinese Tong (slavery leaders)infiltrated the organization. Mission life (1900–1934) Two years after Culbertson's death in 1897, Cameron became superintendent of the Presbyterian Home at the age of 27. She continued the mission of the Home, saving young Chinese immigrant women from sex slavery and indentured service. Contemporary sources referred to this work as "the only foreign mission enterprise ever carried on in the United States". Friends and relatives of these girls would leave clandestine messages for Donaldina at the Presbyterian Home, indicating the house where a girl was held captive. Often, criminal tong members, who nicknamed her "Jesus Woman" and the "White Devil", would threaten Cameron and the home. She once spent a night in a San Jose jail while seeking the release of a Chinese woman. However, Cameron continued her mission. She was sometimes called "Fahn Quai" (), translated variously as "White Spirit", "White Witch", or "White Devil"—a sensational racial epithet that newspaper and magazine reporters helped spread. She was also dubbed the "Angry Angel of Chinatown", which would later become the title for a biography. Once freed, Chinese women were forced to reside at the Presbyterian Home (where they were not allowed outside without an escort) and to convert to Christianity. While some Chinese immigrant women welcomed conversion and saw Donaldina as a savior, nicknaming her "Lo Mo" () (which she translated as " loyal mother"), and others had mixed feelings about this forced conversion. In April 1906, the great San Francisco earthquake and fire forced the evacuation of the Presbyterian Home. Cameron returned the night of the earthquake through the blazing city to retrieve a logbook that detailed her guardianship over the girls at the home, thus ensuring their safety from being forced back into servitude or prostitution. The home was destroyed in the earthquake and was rebuilt in 1907 at 920 Sacramento Street, where it still stands today. Cameron wrote extensively, seeking to gain financial support for her mission, in publications including Women and Missions and a pamphlet titled "The Yellow Slave Traffic". This writing often furthered orientalist depictions of Chinese women, but also challenged popular preconceptions that such women were incapable of integrating into American society. She also founded two homes for Chinese children, many of them orphans or the children of the rescued women. The Chung Mei Home housed
