Bubble tea is popular among every (or almost every) country in Asia. This Taiwanese invention got into the hearts of all people, living on that continent and beyond. I think it might be a nice asset to the stories about Asians and Asia.
P.S. don’t trust pictures that put bubbles on the top of the tea. It’s a marketing lie
And, since we’re talking about popular tea trends, it’s impossible not to mention matcha, which is also one of the most popular drinks among most Asians countries.
