Tsang Tsou-choi

On 23 April 2021, one of the king's piece on Kwun Tong bridge, that was getting renovated after being vandalized, was vandalized again in the same fashion, allegedly by pro-Beijing supporters.

In 2011, Hong Kong curator Joel Chung Yin-chai curated the exhibition "Memories of King Kowloon" at Artistree, Taikoo Place. The exhibition exhibited many of Tsang's handwritten works and some of his belongings. Some of his work has been acquired by the M+ museum in West Kowloon.

When news of his death became known, many people went to take pictures of his work, especially the one in Tsim Sha Tsui Star Ferry Pier (because of the convenience of the location), which was later sprayed with a clear protective layer. Many worried that the government would 'clean up' his remaining public artwork. The Hong Kong authorities promised this would not happen and undertook to analyse ways of preserving his works. However, in 2009 there were protests and questions in Legco regarding the apparent failure of the government to prevent the removal and overpainting of much of his legacy. The Home Affairs Bureau maintained the government's commitment to protecting Tsang's works "depending on the actual situation and feasibility".

He died on 15 July 2007 following a heart attack in Hong Kong. He was 85. Art critic Lau Kin-wai said Tsang spent his final days at an elderly home surrounded by family members. He also said that Tsang's last wish was for another exhibition of his work.

He received international recognition for his work. Photographs of his work have toured in shows, such as "Power of the Word", which began its US tour at Grinnell College's Faulconer Gallery on 6 October 2000. In 2000, he appeared in Clarence Fok's film Queen of Kowloon and in 2001, he appeared in Fruit Chan's film Hollywood Hong Kong. In 2003, he was included in the Venice Biennale. His first major commercial recognition came when Sotheby's auctioned a board, painted by Tsang, for HK$55,000 (USD $7,050) on 31 October 2004.

Tsang Tsou-choi (Chinese: 曾灶財), commonly referred to as the "King of Kowloon" (Chinese: 九龍皇帝; lit. 'Emperor of Kowloon') (12 November 1921 – 15 July 2007) was a Hong Kong citizen known for his calligraphy graffiti.
