What is the relationship between Shaoqin and Erhu?

The biggest feature of Shaoqin is that all the players use the national patent product, an instrument improved from the traditional Huqin by Canadian erhu player Gao Shaoqing.

The barrel design of Shaoqin is a complete revolution of erhu sound transmission system, with the volume increasing and the sound upward; Different from the traditional erhu, the tone of Shaoqin is rich and stable; The second half of the barrel is bent upward, that is, the opening is upward, which increases the volume when playing. These improvements make Shaoqin more expressive than traditional erhu.
