What is it like to drink Qushui? Can you tell me?

The rules for drinking wine in a meandering stream are not complicated. Participants sit at the edge of the water in order of host, guest, and age. I know that the host puts the wine glass into the water from upstream and lets it float down the river and stop there. In front of any guest, the guest would drink all the wine in one gulp, and then recite poems and compose poems based on the banquet content, similar to today's drumming and passing flowers.
