Shangta, a small water town on the west bank of Dianshan Lake in Qingpu District, Shanghai, has been following a folk custom of grandma tea since ancient times. Farmers here, especially grandmas in the countryside, come and go every day, gather together, sit around a few tables and chairs in the living room or corridor shed of the farmhouse, and put homemade local specialties such as pickled amaranth, dried radish, and nine-su beans on the table. They drink tea and chat, talk about the Classic of Mountains and Seas, chat about family matters, keep their mouths busy, and keep their hands busy (doing needlework, etc.) in a happy mood. This kind of life custom of using tea as a gift, treating guests with tea, and exchanging thoughts and feelings has become a custom and etiquette of Shangta over time. It is still difficult to make an accurate investigation of the origin of Shangta Grandma Tea, but many families here still preserve various tea sets handed down by their ancestors: small blue and white porcelain bowls printed with the reign of Jingde in the Song Dynasty; colorful covered bowls with gorgeous patterns; lifelike, simple and elegant lotus Guanyin teapots; thin, fine, small and exquisite teacups, etc. The tools used by Shangta people to make tea are also very traditional: every household has a wall stove in the kitchen, and there is a wind furnace on the field. The boiled water and brewed tea are purer and more fragrant. Since the founding of the People's Republic of China, with the improvement of social civilization and people's living standards. The tea culture taste of Shangta people in drinking "Grandma Tea" has also improved. In addition to maintaining the traditional way of drinking tea, Shangta people have successively extended new tea drinking customs related to several major events in family and life: such as: drinking "happy tea" when getting married, drinking "adding tea" when giving birth, drinking "entering the house tea" when building a house, drinking "top scholar tea" when going to college, drinking "serving the country tea" when joining the army, etc. There are more than 20 ways of drinking tea. During festivals, every household will buy a few kilograms of tea and a few big red papers to package the tea separately. If visiting relatives and friends, tea is always one of the necessary gifts. The fragrant grandma tea is an invisible link and silent fate in the lives of Shangta people.
