"Zhuang Zhou's Dream of Butterfly" is a qin piece composed by Mao Minzhong, a qin master in the Southern Song Dynasty, based on the allusions in "Zhuangzi·Inner Piece·Qiwu Lun". The book of Zhuangzi said: "Zhuang Zhou dreamed of a Hu Die in the past, and a Hu Die is also very vivid. He said that he was suitable for his ambition! He didn't know Zhou. Suddenly he realized that he was like Zhou. I didn't know that Zhou's dream was Hu Die and? Hu Die's dream was Zhou Yu? Zhou? There must be a difference with Hu Die. This is called materialization."

In "Xing Xin Qin Pu", the title of "Zhuang Zhou's Dream of Butterfly" said: "It was written by Mao Minzhong in the Southern Song Dynasty. The song imitated Zhuangzi's leisurely travel. Zhuangzi said in the book. Zhuang Zhou's dream was Hu Die. Then there is Zhou Ran. I don’t know that Zhou’s dream is Hu Die. Hu Die is Zhou. Zhou and Hu Die must be divided. Controlling Qi and swimming in the ruins of the vast desert. It is integrated with heaven and earth. It is one with Taixu. Si Le is beyond the knowledge of vulgar people. Zhuang Zhou Mengdie wrote this realm."

After "Zhuang Zhou Meng Die" in "Xing Xin Qin Pu", he wrote: "The key point of this song is Yiyi. It is not easy to obtain. I forgot both. It was wonderful."

"Zhuang Zhou's Dream of Butterfly" is modeled after the Warring States period qin song "Xiao Yao You". The meaning is "to swim in the ruins of the vast desert with the divine control of the qi. It is integrated with the heaven and the earth. It is the same as the Taixu. Si Le is beyond the knowledge of the vulgar." God and materialization, things and I forget both. Therefore, Mr. Tianhong specifically pointed out in the postscript of "Zhuang Zhou Dream of Butterflies" that the main point of this song is the word "Yi". And Yi is the most difficult to get, "You need to have nothing to worry about. Heart and hands are clean. Chic and smooth. In one go." Xue Qi's irritable qi released his competitive heart, and he was a god without burdens, and he was a device of the Tao. It has its own vision of a spirit that is far away, and those who reach it will meet.
