Last week, a group of international students visit our school. To help them better understand our tea-drinking culture, we took them to the tea room in our school, that I introduced the history of tea-making and different kinds of tea and so on. All the international students were quite interested my introduction.
Then I showed them what to make tea. I sat at a table, explaining every step of the process while making tea. All of them were amazing. They couldn’t wait to have a try for them. Soon the tea room became live with every international student trying to make their own tea. We had a lot of fun, practicing, and enjoy the tea.
At the last, we took a group photo, with cups or tea in our hand, to record this unforgettable experience.
