The flag of Hong Kong features a white, stylised, five-petal Hong Kong orchid tree (Bauhinia blakeana) flower in the centre of a red field. Its design was adopted on 4 April 1990 at the Third Session of the Seventh National People's Congress.[1] The precise use of the flag is regulated by laws passed by the 58th executive meeting of the State Council held in Beijing.[2] The design of the flag is enshrined in Hong Kong's Basic Law, the territory's constitutional document,[3] and regulations regarding the use, prohibition of use, desecration, and manufacture of the flag are stated in the Regional Flag and Regional Emblem Ordinance.[4] The flag of Hong Kong was first officially hoisted on 1 July 1997, in the handover ceremony marking the transfer of sovereignty.[5]
