Answer: There are 2 best ways
The first way, I will call my colleagues to come and ask them to move the cups of water that “were not cleared away in the previous meeting”, then bring up 6 new cups of water.
The second way, if I don’t want to be discovered for my poor hospitality, I will present to the leaders that because it is an epidemic period, I will replace it with bottled water, then bring down 5 cups of water”.
