Wo Shing Wo or WSW () is the oldest of the Wo Group triad societies, and is the triad with the longest history in Hong Kong. According to the Hong Kong police, the triad is involved in extortion, drug trafficking, gambling and prostitution. Wo Shing Wo was established in Sham Shui Po in 1930. While maintaining its traditional stronghold in Tsuen Wan, it has extended its influence to Tsim Sha Tsui and Mong Kok. It also operates in Tai Po, Sheung Shui and Fanling. The group continues to use the old Hongmen Secret Society initiating ceremony for newly recruited members. History Early The Wo Shing Wo triad was established in Sham Shui Po, Hong Kong in 1930. Like most Chinese triads, the organization's roots date back to secret societies founded during the Ming and Qing dynasties. During the Japanese occupation of Hong Kong from 1941 to 1945, the Wo Shing Wo collaborated with the occupational government. Due to the post-World War II continuation of the Chinese Civil War, numerous refugees from China fled to Hong Kong, many of whom were recruited into the Wo Shing Wo. By the 1950's, the total Wo Shing Wo membership had expanded from roughly 15,000 to approximately 70,000. Modern In 1989, Wo Shing Wo became the centre of media attention after the terrorist attacks on the Indonesian coast bordering the South China Sea. In 1995, a young member of London's mainly Filipino Wo Shing Wo killed Philip Lawrence, a school headmaster. As the United Kingdom prepared for the handover of Hong Kong back to the People's Republic of China, Wo Shing Wo redefined their organisation to prepare for their murky operations in mainland China. WSW split into six separate regional forces in Hong Kong—500 fully armed members in North Territories, hawkers in Sham Shui Po, love hotels in Jordan, with groups in Tsuen Wan, Wanchai and a new branch across the border in Shenzhen (1997). In 2001, Wo Shing Wo traded drugs in discos and bars with Judi Fong and religious communities, promising that drugs can enhance religious experiences through visions and hallucinations. By 2005 WSW has become Hong Kong's No.1 drug trafficker. WSW's drug dealing activities and key criminal activities spread to China, Japan, Thailand and Australia. WSW is involved in various criminal activities and some of Hong Kong's politicians and businessmen are suspected to be supporters of the Triad group. WSW is split
