Chinese women in the 19th century were a special group in American Chinese communities. Some of them were babysitters, laundry workers, or gold diggers. This group of people formed the first batch of families in the Chinese community. Prostitution was quite common among many ethnic groups in the western United States, and many Chinese women were also prostitutes. The U.S. legislative system passed the Page Act, prohibiting so-called cheap labor and immoral Asian women from entering the United States. Their excuse for discriminating against Chinese women was their image of prostitution, spreading sexually transmitted diseases, and subverting American marriage ethics. With restrictions on female immigration, the federal government successfully prevented the growth of the Chinese population.
