In the history of Chinese music, only the guqin has left over 3,000 ancient musical notations that can still be played today. The reliable composition dates range from the Sui and Tang Dynasties to the Qing Dynasty. Therefore, I don’t know if it is appropriate to say “ancient style”, haha...
If you want to listen to guqin music, you can search for “guqin” on Xiami.com, and a large number of albums can be listened to and downloaded.
Here I would like to recommend "Lao Ba Zhang" recorded in the early days of the founding of the People's Republic of China, a classic of a generation of guqin masters!
