English propaganda slogan of Taigai milk tea

Bubble tea is a kind of tea mixed with cassava balls. The Taiwan Province name of bubble tea is translated into "bubble tea" (bubble tea). When shaking tea leaves, a thin layer of bubbles will form on the surface. Because of this foaming process, any tea prepared by shaking can be called bubble tea. It was not until tea was brought to non-Asian countries that it was named "bubble tea". Because the most significant difference between bubble tea and other teas is cassava starch at the bottom of the beverage, people think that the "bubble" in bubble tea refers to cassava starch.
