How many Liu Sanjie shows will there be On Saturday, September 20 and Sunday, September 21?

We will sleep in Guilin on September 19, and arrive in Yangshuo late in the PM of September 20. We would prefer to attend the latter show, if there are 2 shows on that date. if not, we would then prefer the first show on September 21. Thre are 7 of us,m and at least 4 are definitely interested in attending, probably all 7 of us.
