1. Tea cups originated from Li Bai, a poet in the Tang Dynasty. It is said that at a tea party, Li Bai thought the color of tea soup was wonderful when he was drinking tea, so he picked up a teacup and poured a few drops of water into the tea. After observing for a period of time, he found that the color change in the water was very subtle, and he was inspired. He asked the craftsman to make a special cup, and the bottom of the cup was concave, so that he could better observe the color change of tea. This is the original form of the teacup.
2. Another way of saying it is that tea cups originated in Ming Dynasty. In the Ming Dynasty, tea tasting activities were often held in social occasions. In order to appreciate the color, rhyme and fragrance of tea soup, people began to use transparent glass cups with concave bottom as tea tasting utensils. With the passage of time, teacups gradually flourished and evolved into various forms and styles in different times and regions.
