The flag of Hong Kong
When the British possession Hong Kong reverted to China in 1997, it remained a Special Administrative Region with its own flag.
The new attractive flag is red with a central emblem of a bauhinia, a five-petalled “orchid”. This flower can be mostly found in Hong Kong in a bright crimson colour and less frequently white as on the pattern. The five red stars within the petals recall the Chinese flag of sovereignty, also designed with a red background.
Whatever connection can be made with the usual interpretation of the Chinese flag, the meaning of the five-pointed stars goes back to the origins of the very old Chinese element theory. It was used to explain the manifestation process of the physical aspects in relation to the yang and yin principles. As everybody knows, nothing occurs in China which is not related to yin and yang.
