Context paragraphs:
Human trafficking in Hong Kong: The Hong Kong Special Administrative Region (HKSAR) of the People’s Republic of China is a destination and transit territory for men and women trafficked for the purposes of commercial sexual exploitation and forced labor.  Hong Kong is primarily a transit point for illegal migrants, some of whom are subject to conditions of debt bondage, sexual exploitation, and forced labor.  To a lesser extent, Hong Kong is a destination for women from the Chinese mainland and Southeast Asia who travel to Hong Kong voluntarily for legal employment in restaurants, bars, and hotels, but upon arrival are coerced into prostitution under conditions of debt bondage.  Some of the women in Hong Kong’s commercial sex trade are believed to be trafficking victims.  Although Hong Kong continues efforts to regulate the thousands of foreign domestic workers from the Philippines and Indonesia currently working in Hong Kong, there appears to be a growing number of Indonesian workers who are subject to exploitation and conditions of involuntary servitude.  Many Indonesian domestic workers earning the minimum wage are required to repay to their Indonesian recruitment agency $2,700 within their first seven months of employment, amounting to roughly 90 percent of a worker’s monthly salary.  Such high levels of indebtedness assumed as part of the terms of employment can lead to situations of debt bondage, when unlawfully exploited by recruiters or employers.  Additionally, the confiscation of passports by some Hong Kong employment agencies restricts the ability of migrant workers to leave their employer in cases of abuse, and places them under further control of their employment agency, leaving them vulnerable to trafficking.

Hong Kong Morris: The Hong Kong Morris (, Cantonese pronunciation: "Heung Gong Gwoo Doi Ying Gwok Mo Tuen", literally Hong Kong Ancient English Dance Platoon) is an English morris dancing team or side founded in Hong Kong in 1974.
