Zhao Feiyan (趙飛燕, c. 32–1 BC)
Zhao Feiyan (Chinese: 趙飛燕, c. 32–1 BC),[1] formally Empress Xiaocheng (孝成皇后), was an empress during the Han Dynasty. Her husband was Emperor Cheng.[2] She was known in the Chinese popular mindset more for her beauty than for the palace intrigue that she and her sister, the also beautiful Consort Zhao Hede engaged in, but unlike most of the famous beauties in Chinese history (such as the Four Beauties), she was often vilified by historians. She was often compared and contrasted with Yang Guifei, the beautiful concubine of Emperor Xuanzong of Tang, because she was known for her slender build while Yang was known for her full build. This led to the Chinese idiom yanshou huanfei (燕瘦環肥), describing the range of the types of beauties.
