This teacup cleverly combines ceramic and plastic in a secure structure. The tea filter is built into the teacup, and the tea leaves can be fully soaked and steamed. The design of the lifting beam makes it easy to control the concentration of the tea to achieve a variety of tastes. It has two upper covers; the large cover is placed upside down for the tea filter, and the small cover is used for dustproof and heat preservation to ensure the taste and temperature of the tea.
