Question: Who was the eldest of the "Four Great Beards"? Passage:Graduating at age 17 in 1940, she established her own troupe with friends from the school. She organised a program of 62 new and traditional plays over a successful 48-day run in Shanghai, starring in 28 of them. Disliking the pressure she came under as an independent young actress, she disbanded the troupe and placed herself under the training and protection of older male actors: Xun Huisheng and Mei Lanfang, two of the "Four Great Dan"; Zhao Tongshan, the greatest "flowery" actor of the time; the "martial clown" Ye Shengzhang; the "educated clown" Ma Fulu; the "painted face" actor Jin Shaoshan; the "martial" actor Li Shaochun; the "Four Great Beards" Ma Lianliang, Tan Fuying, Yang Baosen, and Xi Xiaobo; and the other "old men" Zhou Xinfang and Tang Yunsheng. She also studied under the female impersonators Yu Lianquan and Cheng Yanqiu. The broad range of specialists expanded her repertoire greatly. During this period, Li gave successful performances of The Dragon and the Phoenix, The Courtyard of the Black Dragon, Two Phoenixes Flying Together, and Three Pretty Women. Her career and finances were largely handled by her mother, who was reckoned one of the "Four Famous Mothers" of the opera. She had her first daughter Li Li in 1944.
