Serving Tea: In China, serving tea from the host to his guest has lasted for over 1,000 years. While serving the tea, the host should extend his hands to hold the cup to show respect to his guest. Those who are dainty will usually put the cup onto a saucer or tea-tray, and, when offering the tea, they will use two hands to hold the saucer or tea-board before the chest while saying softly “Enjoy your tea”. The guest, at the same time, should slightly move his body forward and express gratitude.

Covering Cup to Thank the Host: It is a convention for the host to serve tea and add water for the guest. If the guest has drunk his fill and wants to leave, he will usually flatly spread out his right hand with the center of the palm downwards onto the tea cup, indicating, “Thank you. I don’t need more tea."
Substituting Tea For wine: The tradition of substituting tea for wine has existed for more than 2,000 years in China. In the Zhou Dynasty, a prohibition was decreed by Emperor Wuwang, who knew that the Shang Dynasty was just defeated due to alcoholic addiction and corruption. So people began to offer tea to the emperor, while the noble and common people substituted tea for wine too. The custom has come down until today.
Tea after or before Dinner: To clean the mouth and whet the appetite, people usually drink clear, sweet, mild green tea or scented tea before dinner. A short rest should be taken before drinking tea after dinner. Sweet, greasy-removed tea like Oolong and Puer tea is preferred after dinner.
