4) The Lingnan area: This area, consisting of the southern provinces of Guangdong, Guangxi, Fujian and Taiwan, produces Wulong tea, which is renowned both at home and abroad. Advantages of Tea-Drinking Tea has been one of the daily necessities in China since time immemorial. Countless numbers of people like to have their after-meal cup of tea.

In summer or in warm climates, tea seems to dispel the heat and bring on instant cool together with a feeling of relaxation. For this reason, tea-houses abound in towns and market villages in South China and provide elderly retirees with the locales to meet and chat over a cup of tea.

Medically, the tea leaf contains a number of chemicals, of which 20-30% is tannic acid, known for its anti-inflammatory and germicidal properties. It also contains an alkaloid (5%, mainly caffeine), a stimulant for the nerve center and the process of metabolism. Tea with aromatics in it may help resolve meat and fat and thus promote digestion. It is therefore, of special importance to people who live mainly on meat, like many of the ethnic minorities in China. A popular proverb among them says, "Rather go without salt for three days than without tea for a single day".

Tea is also rich in various vitamins and helps smokers discharge nicotine from their systems. After "wining", strong tea may prove to be a sobering pick-me-up. However, this does not mean that the stronger the tea, the more advantages it will yield. Too much tannic acid will affect the secretion of gastric juice, irritate the membrane of the stomach and cause indigestion or constipation. Strong tea taken just before bedtime will give rise to occasional insomnia. Constant drinking of overly strong tea may induce heart and blood-pressure disorders in some people, reduce the milk of a breast-feeding mother and put a brown color on the teeth of young people. It's not difficult, however, to ward off these undesirable effects-simply don't make your tea too strong.
