Nalan Xingde, Zhu Yizun and Chen Weisong are also called "Three Musts" in Qing Dynasty. He has made great achievements in Ci studies, and is a famous poet since Li Yu in the Five Dynasties and Yan in the Northern Song Dynasty. His lyrics are "touching and graceful, the highest in the world" (in Zheng Zhenduo), with profound thoughts, fresh style and unique lyrical objects. Nalan is virtuous, and his poems focus on homesickness, homesickness and homesickness. Gu Zhenguan said: "Rong Ruo's Ci is a sad place that people can't bear to read." When talking about Nalan Xingde, Wang Guowei said: "Nalan Rong Ruo sees things with natural eyes and expresses his feelings with natural tongue. This time, when I first entered the Central Plains, I didn't smell of Han people, so it can be true. Since the Northern Song Dynasty, there has been only one person. "
Most of the poems about drinking water are true feelings, and Nalan himself advocates that "poetry is the true voice, and the matter of temperament is also". His ci is the concrete practice of his thought. In terms of language features, drinking water words pursue "natural carving", that is, they do not excessively pursue rhetoric. He advocates the free expression of temperament and opposes carving and pretense. Nalan opposes carving, not that he doesn't pay attention to tempering, but that he advocates not showing traces of axes and chisels, but that he should temper artistically to the degree of returning to nature.
