A teapot is an instrument for making tea, which can usually hold enough water and has the functions of filling and discharging water. The design of teapot usually includes a long handle, so the purpose of this design is to facilitate grasping and pouring water to avoid scalding. In addition, teapots usually have exquisite shapes and designs, which not only increase their aesthetic value, but also enhance the overall atmosphere when drinking tea.
In contrast, fair mug's design is smaller. It is usually used to taste tea or coffee, or to taste different wines. Fair cups usually have exquisite designs, which can better display the color and aroma of drinks. Fair cups play the role of even tea soup in tea ceremony, ensuring the consistency of each cup of tea soup and embodying the spirit of "fairness".
To sum up, although both teapot and fair cup are related to tea, there are obvious differences in design and function. Teapots are mainly used for making and pouring tea, while fair mug is mainly used for making even tea soup and tasting tea.
