In the 1980s, when freshmen of Peking University entered the school, an interesting thing happened: a freshman named Kong Mingdong just walked into the campus of Peking University with a lot of luggage. He wanted to go to another department to find his fellow villagers first, but he was worried about too much luggage and went to the "unnamed lake" in Peking University. Mr. Ji Xianlin happened to pass by here. Seeing Ji Lao dressed simply and wearing the red school badge of Peking University, he decided that this man was the old guard of the school, so he took the initiative to greet Ji Lao and said, "Old guard, would you please look after my luggage for me?" I have to do something. "Ji Lao replied:" Good! But please come back as soon as possible. " As a result, the hole went for three hours. Ji Lao is very helpless, just reading a school magazine in his hand, and Kong hasn't come back after reading this magazine. It's no use worrying. Ji Lao had to wait faithfully beside his luggage for more than three hours. Kong Dong Qing came back excitedly and said to Ji Lao, "You have helped me a lot. I used this time to find all the northeast villagers who were admitted to Peking University with me this year. Please come to the Chinese Department for me if you have anything in the future. "
