The Regional Flag of the Hong Kong Special Administrative Region of the People's Republic of China depicts a white stylised five-petal Hong Kong orchid tree (Bauhinia × blakeana) flower in the centre of a Chinese red field. The design of the flag is enshrined in Hong Kong Basic Law, the territory's constitutional document, and regulations regarding its use, prohibition of use, desecration, and manufacture are stated in the Regional Flag and Regional Emblem Ordinance. This led him to incorporate the flower into the flag to represent Hong Kong.
