What knowledge of tea ceremony must a tea artist know in China?

What China tea ceremony do I have to learn?

I think tea ceremony is the most common mutual respect between people.

Do you still need to study?

Do you need to redefine it?

But tea ceremony knowledge

But it is the most lacking. How to make good tea if you don't know tea?

Learn tea or tea ceremony,

You have to learn tea.

There is tea in the heart, which makes tea a tea ceremony; There is no tea in the heart, and the tea ceremony becomes tea.

Does everyone have tea in their hearts? If not, please don't call yourself a tea man or a tea artist.

Otherwise it's a joke.
