今天，我的学生说他去参加了一个重要的宴会，宴会中有香港人和韩国人，但是在韩国人中，只有他会说普通话，所以他和香港人聊得很开心，给他们留下了深刻的印象。 Today, my student said he went to an important banquet. There were people from Hong Kong and Korea at the banquet, but among the Koreans, only he could speak Mandarin. So he had a great time talking with the people from Hong Kong and left a deep impression on them.
