People in the office will make tea and say.

See the boss, see what guests, see what to talk about, see if people are interested in drinking tea or just chatting over tea, talk about business while drinking or go to dinner after drinking wine, all of which should be prescient. Kung fu tea is always added to others. If you have something important to do, you should ask the boss for leave, and the boss won't let you go, so you can continue.
