刘因
元
Liu Yin, courtesy name Mengji and literary name Jingxiu, was a major Yuan dynasty Neo-Confucian scholar, poet, and sanqu writer from Rongcheng in Xiongzhou. Known for his learning from an early age, he briefly served under the Yuan court as Chengdelang and Right Adviser, but resigned because of his mother's illness. Later, when Kublai Khan summoned him again, he declined on grounds of illness and avoided prolonged official service. Liu Yin was deeply learned and wrote works such as Jingxiu Ji. His poetry and songs often combine moral self-discipline, historical reflection, and a clear awareness of impermanence. "Human Moon Round" is one of his most philosophical sanqu pieces.
