Meeting a foreign classmate during your study is a fate and friendship. This will help your spoken English a lot. You will be a lifelong friend after graduation.
1. Foreigners value creativity rather than value when giving gifts. I recommend a bottle called a sunshine jar to her. This bottle looks very ordinary, but in fact, at night, it will release the sunlight absorbed from the sun during the day into light. Let her have such a bottle on Christmas Eve.
2. China is the land of silk. Foreign girls like Chinese silk very much. Why not give her a long silk wallet as a gift? If a foreign girl has this kind of wallet, she will feel very fashionable and have a special style. It will be even better if it is matched with a Chinese cheongsam or traditional Chinese clothing.
China's Peking Opera is also a national treasure. Foreigners are also very interested in it. Why not give her a set of pens with Peking Opera masks as a birthday gift. There are various characters. Such a gift will make her friends and relatives envious when she returns home.
