China is a country with a time-honored civilization and a land of ceremony and decorum.Whenever guests visit,it is necessary to make and serve tea to them.In the course of serving tea,the host should take careful note of how much water is remaining in the cups and in the kettle.Usually,if the tea is made in a teacup,boiling water should be added after half of the cup has been consumed; and thus the cup is kept filled so that the tea retains the same bouquet and remains pleasantly warm throughout the entire course of tea-drinking.Snacks,sweets and other dishes may be served at tea time to complement the fragrance of the tea and to allay one's hunger.
