Tsang Tsou-choi (), commonly referred to as the "King of Kowloon" () (12 November 1921 – 15 July 2007) was a Hong Kong citizen known for his calligraphy graffiti. Early years Tsang was born in Liantang Village (), Koyiu (Gaoyao), Shiuhing (Zhaoqing), Kwangtung (Guangdong), Republic of China. He travelled to Hong Kong at the age of 16 as a worker, poor and barely literate. He began to mark the streets of Hong Kong with his distinctive graffiti at the age of 35.
