On May 24th, it was reported that at the latest graduation ceremony of the University of Maryland, Charityi Yang, an international student from China, said in his graduation speech that he chose to study in the United States because of the "fresh air" there. She said that you need to wear a mask when you go out in China's hometown, or you will get sick. Once the latest news of this remark spread on social networks in China, it immediately caused an uproar. In response, the Ministry of Foreign Affairs of China responded on 24th. According to the website of Deutsche Welle Radio on May 23, Charityi Yang said: "I felt another kind of fresh air at the University of Maryland, and this experience made me happy forever-the fresh air of freedom of speech." The latest news of this speech caused an uproar on social networks in China. Some netizens criticized Charityi Yang, who is known to be from Kunming, for describing the air quality in his hometown as "untrue". According to the website of Lianhe Zaobao on May 23rd, Charityi Yang apologized on the evening of 22nd after the latest news of this remark caused an uproar. She responded: "I was deeply disturbed by the unexpected response to this speech. I deeply love my motherland and hometown, and I am deeply proud of the prosperity and development of my country. I also hope that I can use what I have learned abroad to promote China culture and make positive contributions to the country in the future. The speech only shared my experience of studying abroad, and it didn't mean to deny or belittle my country and hometown at all. I sincerely apologize here and sincerely hope that everyone will understand and learn from it in the future. At the same time, I hope there will be no more interpretations or even personal attacks. Thank you! " In response, China Foreign Ministry spokesperson Lu Kang said in response to a reporter's question on May 24th that "any China citizen should be responsible for everything, not only for China, but also for any problems". Regarding whether the Embassy of China in the United States is involved in this matter and whether the China government has issued guidance opinions for international students, Lu Kang said that "I have never heard of such a situation". Summary: The Ministry of Foreign Affairs should take a responsible stance on the graduation speeches of international students from the University of Maryland. In addition, Lu Kang said: "I think many netizens think that any country has its own side to be proud of, and at the same time, there are some problems in the development of each country. On what occasions and ways does a citizen comment on his country? I believe that everyone can easily feel his/her feelings for the motherland. " Lu Kang said, "I also noticed that the student you mentioned later made a public statement or apologized. She said that she loves her motherland and is willing to go back to China to make her own contribution after her studies. If this news is true, I would like to say that there are many international students in China at present, and these young students' views and understanding of some things may go through a process of development and change after going abroad. However, as long as they finally love their country from the bottom of their hearts and are willing to make contributions to the motherland, I believe the China government will encourage, support and welcome them.
