The symbolic serving and drinking of wine on various occasions and in different places can convey many meanings. It can express either joy or sorrow. In China, there is a saying that 'a thousand cups of wine is not too much when bosom friends meet together', which indicates the happiness between two confidants; whereas a verse by Li Bai, a noted poet in the Tang Dynasty (618 - 907), says, 'releasing melancholy by wine, but adding more,' suggested a touch of sadness. There are frequent references to wine in well-known legends, as for example - "to taste the sweet osmanthus wine on the moon, produced by the beautiful fairy Chang'e when she felt lonely, is everyone's dream".
Nearly all important occasions are celebrated with alcohol. The Spring Festival, which is a favorite time for family reunions, is probably one of the most significant when rejoicing is expressed by social drinking. During the Double Ninth Festival, people drink chrysanthemum wine to ward off evil and to wish their elders good health and longevity. Of course, no wedding ceremony is complete unless the happy couple symbolizes their love for each other by linking their arms to drink to their future happiness (jiaobeijiu), after which they offer a dutiful toast to their parents to thank them for the care they have given to them as children. Similarly, birthday celebrations and the ceremony to mark the 100th day following the birth of a baby will be solemnized with a toast of wine or spirits. In South China, when a baby girl is born, her parents will brew alcohol for her, bury it underground and keep it until she marries. Then they take the jar up and paint auspicious pictures upon it to give greetings.
Each ethnic group has some form of alcoholic drink with which to celebrate special festivals. For example, around the Spring Festival, Korean people drink their 'suijiu' to which is added rice, root of the balloon flower, cinnamon and, red chili and so on, to ward off demons.
When drinking wine or spirits at table, both the host and the guests are expected to observe certain rules of etiquette and behavior.
The glass should be full of wine, else the guest will think they are lacking due respect. The elders and superior person or persons present should always be served first.
A toast represents esteem, while refusing to participate in a toast shows the great irreverence and a lack of politeness. Should a guest be genuinely unable to take a drink then he has to find another to do it for him in order to save face.
When making a toast, everyone is required to stand and lightly touch each others' cup, ensuring that the junior's cup is held lower than that of their superior. The cup should be emptied and inverted to show that no wine remains. Drinking with a single draught symbolizes boldness and an uninhibited character. Those who cannot manage to do so should explain in advance in order to receive a kindly understanding of their situation and thus ensure that no one is offended.
