"Holding" has governance; The meaning of service. If understood as, it is equivalent to the host of today's wedding, funeral and other activities; If you are a waiter, you are equivalent to a waiter.

Broadly speaking, anyone who helps the host family manage the affairs, big or small, can be called a guest (also a guest), and "teacher" means to show respect and gratitude.

I think so.
