What kind of spiritual qualities did Academician Li Xiaowen, who was once a smash hit on the Internet, gain popularity among young people?

Approachable, many people are an old man, wearing canvas shoes and holding Erguotou every day. I didn't expect to be a knowledgeable scientific academician. This academician looks very approachable and wears ordinary clothes, unlike other academicians who wear suits and ties, which makes people look impressive. Once I went to class, I was stopped by the security guard and thought it was an old man who collected garbage. Academician always tells this story as a joke to people around him. It is such an approachable way of doing things that everyone feels particularly easy to get along with and is liked by young people. Seeing this photo, I believe many people don't believe it. This is a great academician of our country, dressed so simply. In fact, there are many such great people, doing the greatest things and living the most ordinary life. Compared with such a person, I suddenly feel extremely ashamed. Usually I don't pay much attention to my academic problems at school. At school, my parents will give me living expenses, live a carefree life and seldom think about other things. I want to eat well and sleep well every day. And I usually tell my parents what I want to buy, and my parents will basically be satisfied. I feel that it is a material problem to pursue too much at ordinary times. It is really pitiful to face this kind of self-suffering. In fact, I like this grandfather very much when I look at the photos. He looks cute, just like his grandfather. In this way, we can get along better with classmates, teach students how to graduate, and pass on our knowledge to the younger generation without reservation, hoping that knowledge can be better spread and contribute to education. In fact, when I saw this grandfather, I thought of many of his former teachers, and it was the same. Standing on the platform, he dressed very simply. I can't bear to change a pair of shoes after wearing them for several years, but standing on the podium is really amazing. Maybe I can't see such a great man with my own eyes, but I have seen in many videos that grandpa is full of energy and keeps the vitality of young people, regardless of individuals, and only contributes to more people.
