Commonly known as "Taiwan". A red field, with a blue canton containing a 12-ray white sun. This flag flew over Mainland China until 1949, and is presently flown in Taiwan and other islands under the control of the ROC. This flag can be sometimes seen in Mainland China, for historical and unofficial use.
A white, five-petal Bauhinia blakeana on a red field with 1 star on each of the petals. The Chinese name of Bauhinia × blakeana has also been frequently shortened as 紫荊/紫荆 (洋 yáng means "foreign" in Chinese, and this would be deemed inappropriate by the PRC government), although 紫荊/紫荆 refers to another genus called Cercis. A statue of the plant has been erected in Golden Bauhinia Square in Hong Kong. Although the flowers are bright pinkish purple in colour, they are depicted in white on the Flag of Hong Kong.
