When the Communist Party of China took power in 1949, mainland China was put under strict law enforcement and organised crime diminished. Triad members then migrated south to the British crown colony of Hong Kong for the continuance of their business.

It was estimated that in the 1950s, there were 300,000 Triad members in Hong Kong.
At that time there were eight main triad groups and they had divided Hong Kong up into geographic areas and ethnic groups that each group was responsible for controlling.

The eight main ones at that time were the Wo Shing Wo, Rung, Tung, Chuen, Shing, Sun Yee On,14K, and Luen.

This migration of ‘my’ triad, the Sung Society, from Shanghai to Hong Kong, is covered in my novels. The other triad society I include in my books, the ‘Green Gang’, was an actual triad, but weakened by the death of its charismatic leader, Du Yuesheng, it never thrived in Hong Kong.
