《文心雕龙·事类》
陈思王曹植，可算是群才中的英俊了，但他在《报孔璋书》中说： 葛天氏时的音乐，千人合唱，万人相和，听了这种音乐的人，对古代的《韶乐》和《大夏》都有所轻视了。 
陈思，群才之英也，《报孔璋书》云∶ 葛天氏之乐，千人唱，万人和，听者因以蔑《韶》、《夏》矣。 
Chen Si Wang Cao Zhi can be regarded as a hero among the heroes, but he said in the book to Kong Zhang: The music of Ge Tian's time was sung by thousands of people and accompanied by ten thousand people. Those who listened to this kind of music all looked down upon the ancient Shao Le and Da Xia.
