"Dongting Qiusi" is a qin piece of the Ming Dynasty, the author is unknown. This piece is based on the meaning of autumn in Dongting. Clear water and sky high, smoke waves vast. The realm of life, after years of washing and precipitation, is as clear as the water and sky in Dongting. The so-called: "I once put a flat boat back to Chutian, and I was saddened by tears. The moon in Xiangshan Mountain in my twenty-year dream is clearly on the seven strings tonight."

This score was originally found in "Xilutang Qintong". Since then, it has been collected in "Qin Shu Daquan", "Songxian Pavilion", "Dahuan Pavilion", "Ziyuantang", "Tianwen Pavilion", "Wuxue Mountain Room", "Chengyitang", "Zhaoyu Room Qin Score", "Xing Xin Qin Score" and many other collections.

The existing audio-visual materials for this piece are relatively rich, including: "Dongting Autumn Thought" played by Zha Fuxi, Li Kongyuan, Zhu Su, Xie Xiaoping, Wang Huade, Wu Ziying, Gong Yi, Tang Shizhang, and the tutor Mani Tianhong. Each has its own characteristics. I personally like Mr. Cha's simplicity, simplicity and elegance. Zhu Xizhi's "Autumn Thoughts in Dongting", elegant and meaningful, is also a good product. The teacher's "Dongting Autumn Thought" is elegant and broad-minded, with a very ancient style. Qin Xin thought that although this piece was small, it was actually a classic, and I could listen to it again and again and scrutinize its meaning.

"Xing Xin Qin Score" Dongting Qiusi Problem Solving: Ming music, the author is unknown. Write Dongting Yanbo, clear and vast. Autumn is high and refreshing, making people feel ups and downs. The realm of life is contained in the shadow of its blue waves. The so-called: once put a flat boat back to Chutian, Qing ape tears and bamboo thoughts are sad. In my twenty-year dream, the moon on Xiangshan Mountain is clearly on Qixian tonight.

"Xing Xin Qin Pu" Dongting Qiusi postscript: The author of this song is not recorded. The score first appeared in Ming Wangzhi's "Xilutang Qintong". Later, it was also seen in the "Qin Shu Daquan", "Songxian Pavilion", "Da Huan Pavilion", "Ziyuantang", "Tianwen Pavilion", "Wuxue Mountain Room" and many other collections. The tune has a high pitch and should be an ancient tune. However, because there is no documentary record and there is no way to verify its age, it is designated as Mingqu.

The notation for this song is relatively brief. Some of them are inflected, and the notes in each score are different, but the whole has not changed much. After the "Ziyuantang" in the Qing Dynasty, its spectrum changed greatly compared with the Ming spectrum. "Wu Xue Shan Fang" even changed to a slow palace tune.

Even in modern times, Mr. Cha Fuxi's "Dongting Autumn Thoughts" is very famous. Its score is revised according to the "Qin Shu Daquan", which is included in his "Zhaoyu Room Qin Score". "Zhaoyu Shiqin Score" is a collection of scores written by Mr. Zha, which contains eight of his good piano pieces, which were mimeographed and circulated.

Tianhong's "Autumn Thoughts in Dongting" is a combination of "Songxian Pavilion" and "Da Huan Pavilion".
