Anti-Mui Tsai Society

The Anti-Mui Tsai Society was a social-reform organisation established in Hong Kong on 8 August 1921 to oppose the mui tsai system. Mui tsai referred to a customary arrangement in which girls, usually from impoverished families, were transferred or sold to wealthier households as domestic servants. In some cases, the girls were described as potential future daughters-in-law; in others, the arrangement exposed them to severe exploitation, forced domestic labour, or entry into the sex trade. Although the practice was rooted in Chinese social and economic customs, its continuation in colonial Hong Kong created a conflict with British anti-slavery law and with the colonial administration's obligations under wider international agreements. The society emerged after the mui tsai issue had attracted growing attention from Chinese Christians, British reformers, labour organisations, and the press. For many Chinese Christian activists, the campaign was part of a broader movement for social improvement and greater public accountability. For British observers, the issue raised questions about whether colonial authorities were tolerating a form of slavery or slave trafficking under the guise of a private household custom. The administration had historically treated the matter as an internal concern of Chinese families and was reluctant to intervene directly, despite formal prohibitions on slavery and slave trading. The Anti-Mui Tsai Society helped turn the issue into a sustained public and political campaign. Its activism included criticism of official inaction and support for press attention in Britain and Hong Kong. The society's opponents included the Society for the Protection of the Mui Tsai, which received backing from prominent members of the Chinese merchant community, including Lau Chu Pak, Ho Fook, and Ho Kum Tong. The dispute therefore involved not only the protection of girls but also competing interpretations of Chinese custom, colonial authority, racial politics, Christian reform, and the limits of state intervention in domestic life. An early administrative response required mui tsai girls to be registered, with the stated purpose of preventing further trafficking and enabling official oversight. Reformers considered this approach inadequate because registration was weakly enforced and could leave existing arrangements intact. International pressure increased after Britain became subject to the 1926 Slavery Convention of the League of Nations. The issue consequently became an international embarrassment and a matter of imperial compliance rather than solely a local controversy. In response to continuing political pressure, the Hong Kong authorities enacted the Female Domestic Service Ordinance in 1929. The ordinance required mui tsai girls to be registered by 31 May 1930 and provided for inspections intended to verify their treatment and payment of wages. After the registration deadline, further registration—and therefore the lawful continuation of the system through new registrations—was to cease. The reforms represented a significant legal response to the campaign, although contemporary and later assessments questioned how effectively the rules were implemented in practice. The society is historically significant as an example of organised Chinese Christian and labour-linked activism in colonial Hong Kong. It also illustrates how local reform campaigns could gain force through British media, imperial politics, and international anti-slavery institutions. The organisation is not documented here as a commercial brand or as a continuing business enterprise; its inclusion in a brand-style encyclopedia reflects its identifiable organisational name and historical public identity.

The mui tsai system existed in Chinese communities, including colonial Hong Kong, as a form of dependent domestic service in which girls from poor families were transferred or sold to wealthier households. The girls could be described as servants or prospective daughters-in-law, but the arrangement often involved unequal power, inadequate freedom, and the risk of physical, economic, and sexual exploitation. Some girls were reportedly diverted into the sex trade. The practice raised a legal and moral contradiction in Hong Kong because British law formally prohibited slavery and slave trading, while colonial officials commonly treated household arrangements involving Chinese families as a private cultural matter. During the early twentieth century, the issue became increasingly visible to Chinese Christians, British reformers, labour activists, and newspaper audiences. The Anti-Mui Tsai Society was founded in Hong Kong on 8 August 1921 amid this growing concern. Its campaign connected local social activism with wider anti-slavery arguments and called for an end to the sale or transfer of girls under the mui tsai system. The organisation's emergence also reflected the growing willingness of Chinese Christian and labour-linked groups in colonial Hong Kong to challenge both social practices and official passivity. The society's position was contested by the Society for the Protection of the Mui Tsai, which was supported by influential Chinese merchants such as Lau Chu Pak, Ho Fook, and Ho Kum Tong. The dispute was not simply a disagreement over one labour arrangement. It involved questions about Chinese customary authority, colonial racial politics, Christian reform, the power of merchant elites, and whether the government should regulate domestic relations within Chinese households. Anti-mui tsai campaigners used the British press and political lobbying to portray the system as a form of child slavery that required state intervention. The first regulatory responses relied heavily on registration. Officials sought to identify mui tsai girls and place their treatment under some form of supervision, but campaigners argued that the system remained effectively intact because registration was not properly enforced. The international environment later changed the political stakes. Britain's participation in the League of Nations and its obligations under the 1926 Slavery Convention made the continued existence of the mui tsai system a matter of imperial and international scrutiny. After sustained pressure, the Hong Kong government enacted the Female Domestic Service Ordinance in 1929. The law required all mui tsai girls to be registered by 31 May 1930. It also contemplated inspections to ensure that girls were treated properly and received wages. Following the deadline, no further registration was to be permitted, which was intended to prevent new girls from entering the system through officially recognised arrangements. Although this represented a major formal change, the effectiveness of the policy remained disputed because enforcement and protection of girls already in service were difficult. The Anti-Mui Tsai Society's historical importance lies in its role in making the system a public issue and in linking local activism to imperial law and international anti-slavery standards. The organisation is remembered as part of the broader anti-mui tsai movement rather than as a commercial enterprise. Its story demonstrates how reform groups, newspapers, churches, labour organisations, and international institutions could jointly pressure a colonial administration to regulate a practice that officials had previously treated as a private custom.

  Support for statutory registration and inspectionStrategy

  Background

  Earlier registration measures were viewed by reformers as insufficiently enforced. International scrutiny following the 1926 Slavery Convention increased pressure for a more formal response.

  Action taken

  The campaign supported the move toward the Female Domestic Service Ordinance, which required registration by 31 May 1930, provided for inspections and wage oversight, and prohibited further registration after the deadline.

  Aftermath

  The ordinance established a legal mechanism intended to end new mui tsai registrations, but the practical effectiveness of enforcement and protection remained disputed.
