It is a street where cars come and go at dusk in winter, and people are in a hurry. They wore thick down jackets, curled up, covered their red cheeks and rubbed their frozen hands from time to time. The flowers withered, and the grass hid in the embrace of the earth and refused to come out. Almost all the leaves on the broad-leaved trees have fallen off, and the remaining dead leaves hang on the trees, shivering in the cold wind. Only tall and straight pine trees still stand on the street. This day is the day when volunteer Xu Guide Nan works. ...

Ten-year-old Gu Bing came home from school and passed the crossroads where volunteer Xu Nan worked. "How to get to Super 8 Hotel?" "Turn left and go straight." "Where is the nearest bus stop?" "Go straight and turn right, and you can see it." "Hello, how can I get to Kangtai Supermarket?" "Turn left at the next intersection, and you will arrive. He is on your right. " ..... A series of questions about asking for directions made Xu Nan too busy to even have a sip of hot water. What if I don't drink water this winter? Gu Bing thought and ran to the porridge shop next to the crossroads.

Gu Bing took out his only five yuan pocket money and handed it to the clerk. After a while, a bowl of hot millet porridge was brought up by the clerk. Gu Bing quickly packed the porridge, held it gently in her arms, walked quickly to Xu Nan's post, carefully took it out and put it on a spoon, handed it to Xu Nan, and said with concern, "This is the millet porridge I bought in that porridge shop. You must eat it while it is hot. " Xu Nan gratefully accepted the steaming porridge bowl, and her eyes filled with tears. He quickly asked, "Thank you very much, little friend. What's your name? " But Gu Bing said: "Learn from Lei Feng, do good deeds, and don't leave a name!" Passers-by left Gu Bing with approving eyes.

Gu Bing watched Xu Nan nibble at the millet gruel, and then quickly returned to work, while Gu Bing showed the way to pedestrians and vehicles on the road with him. During his service, Gu Bing experienced the joy and pride of helping others. Because he has made contributions to society and provided convenience for others.

The cold wind is howling, but in the busy street, the hearts of Xu Nan and Gu Bing are warm. ...
