The "Shaoqin" is an improved instrument based on the erhu by Gao Shaoqing, a Canadian erhu player, and named it "Shaoqin". Like the erhu, it has a piano tube, a piano rod, a piano shaft, and a piano bow. Still belongs to Erhu.

The Shao Qin is different from the traditional Erhu:

2.1. The Qin tube has structural changes. The opening of the piano tube is curved upward at the rear half, causing the sound to go upwards, thus increasing the volume by one-third, and eliminating the need for an amplifier when performing in a concert hall. The vocal range is also much wider and the expressive power is richer.

2.2. The cover of the piano tube is made of special artificial leather, which is environmentally friendly, achieves uniform high and low sounds, and also adds a bit of guttural timbre to the human voice.

2.3. The piano axis uses a modern high-precision gear axis, which has high precision and does not run out of strings. It can be adjusted with ease regardless of large-scale tuning or fine-tuning.

In Canada and the United States, Gao Shaoqing has frequently used the Shaoqin to dialogue with jazz, rock music, country music, etc., and even used the Shaoqin to successfully perform "Butterfly Lovers" with the famous Austrian Symphony Orchestra with its comfortable volume.

"Butterfly Lovers" is a Chinese-themed violin concerto that has moved countless people. Played with the "Shao Qin", the "muffled pathos" of the Erhu is slightly reduced. The bass range is richer than the violin, and the high notes are The sound quality is as bright and crisp as a violin, which is simply unmatched by the traditional erhu.

"Shao Qin" vividly expresses various emotions such as gracefulness, delicacy, sadness, boldness, madness, calmness, and calmness. Its appearance is fashionable and advanced, noble and elegant, and it is both the most modern and the most traditional.
