Most people in Guangdong are healthy, and most families have the habit of drinking tea. Tea made from mountain spring water tastes better and is more nutritious. Because mountain spring water permeates many sandstone layers, it is equivalent to being filtered many times in nature, with few impurities and soft, clear and sweet water quality. Dinghu Spring is also an old name in Guangdong. For example, Taotaoju and other well-known early tea houses all use Dinghushan spring water to make tea and soup.
