A group of international students visited our school in last week. To help them better understand our tea-drinking culture, I take them to the tea room in our school but introduced the history of tea-making and tea culture to them. All the international students was quite interested in my introduction. Then I showed them what to make tea. I sat at a table, slowly explain every step of the process while making tea. All of them were so amazing that they couldn’t wait have a try themselves. Soon the atmosphere in the tea room became cheerful and lively and we had a lot of funs practising making tea. In an end, we took a group photo to memorize this unforgettable moment.
