Sanpaotai, also known as "Gaiwancha", is a traditional tea drinking custom of Hui people. It is the first in Chengdu and unique. The so-called "cover bowl tea" includes three parts: tea cover, tea bowl and tea boat, so it is called cover bowl or three batteries, which means "heaven covers it, tea covers it; Earth bearing, tea boat; People are educated, tea bowls. " It contains the simple humanistic thought of Shu people. A tea boat, also known as a tea boat, is a saucer that carries a tea bowl. According to legend, it was invented in Chengdu by the daughter of Cui Ning, our timekeeper, during the middle age of Tang Dezong Construction (780-783). Cui Ning's son cleverly invented a wooden board to support the teacup, because the original teacup had no substrate and often burned his fingers. In order to prevent the cup from falling off easily when drinking tea, she tried to circle the center of the wooden plate with wax to make the cup easy to fix. This is the earliest tea boat. Later, the tea boat was changed to a lacquer ring instead of a wax ring, which was convenient for everyone. In later generations, the ring bottom became more and more novel and varied in shape, like a ring bottom cup. A unique tea boat culture was born in Chengdu, also called Gaiwan tea culture. This unique way of drinking tea gradually developed from Bashu to the surrounding areas, and later spread throughout the south.
Hui people build bowls also called Sanbao. Because the cover bowl for holding water consists of a tray, a bell-shaped tea bowl and a tea cover, it is called a cover bowl or three batteries. Gaiwancha has different tea names due to different ingredients, such as brown sugar brick tea, white sugar tea and rock sugar Wo Wo tea. Brew with boiling water. Serve tea to the guests before eating. When pouring tea, uncover the lid of the bowl in front of the guests, put it into the tea material, then cover it with boiling water and hold it in both hands to show respect for the guests.
