Zhao Feiyan

Zhao Feiyan (Chinese: 趙飛燕,  ? – September or October 1 BC), formally Empress Xiaocheng (孝成皇后), was a Chinese courtesan and empress. She was an empress during the Han dynasty. Her husband was Emperor Cheng. She was known in the collective consciousness of Chinese society more for her beauty than for the regal presence that she and her sister, the Consort Zhao Hede engaged in and exuded, but unlike most of the famous beauties in Chinese history (such as the Four Beauties), she was often vilified by her own sisters. She was often contrasted with Yang Guifei, the 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 huanfei yanshou (環肥燕瘦, literally "fat Huan, thin Fei"), describing the range of beauty types. Later, the idiom was applied to literary styles that could be either verbose or sparse, but equally effective.
