Three-minute crosstalk or double reed

Three-minute crosstalk is really difficult to edit ... I recommend two videos to you. One is The Return of Degang Guo, which contains more than 10 small baggage. Pick a few and put them together for three minutes. The other is Degang Guo's "big double spring", in which more than n small double springs are connected together. It is enough to pick just a few, but it requires the skill of the performer.
