Which is more difficult, Cang or Guzheng?

Pale Yin Ge is very difficult. Cang's music score is highly complicated, which requires the flexibility and strength control of the player's fingers. Players need to have high playing skills and proficiency to complete solo, and Ding Fengbo is a guzheng performance-level repertoire, which belongs to the professional level, but the requirements for skills in the performance process are low, mainly to examine the player's sense of music and emotional expression.
