Songs to be played with ancient musical instruments such as Qin, Xiao and Di. .

Do you mean folk music and ancient songs? The shape of ancient musical instruments has changed more or less since it was handed down to the present.

I'm really not sure about the song. Music can provide you with some search:

Zhang Weiliang's Wild Goose in Pingsha, flute and piano ensemble;

Beside the dressing table, Xiao and Zheng;

Guqin music "plum blossom three lanes";

Bass flute "Dresser Qiu Si";

Wait a minute. The artistic conception of these songs is not bad.
