It was a street full of cars and people at dusk in winter, and people were walking hurriedly on the street. Wearing thick down jackets, they huddled up, covering their red cheeks, and rubbing their frozen hands from time to time. The flowers withered, the grass hid in the embrace of the earth and refused to come out, the leaves on the broad-leaved trees almost fell off, and the few remaining dead leaves hung on the trees shivering in the cold wind. Only the tall pine trees still stood. By the street. Today is the day when volunteer guide Xu Nan works...

Ten-year-old Gu Bing came home from school and passed the intersection where volunteer Xu Nan worked. "How to get to the Super 8 Hotel?" "Turn left and go straight." "Where is the nearest bus stop from here?" "Go straight and turn right and you will see it." "Hello, how to get to Kangtai Supermarket?" " Just turn left at the next intersection and he will be on your right. "...A series of directions questions kept Xu Nan so busy that he didn't even have time to take a sip of hot water.

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 out by the clerk. Gu Bing quickly packed the porridge, gently held the packed porridge in his arms, walked quickly to Xu Nan's work station, carefully took out the porridge, put it on a spoon, and handed the porridge to Xu Nan. He said with concern: "This is the millet porridge I bought at that porridge shop. You must drink it while it's hot." Xu Nan gratefully accepted the steaming bowl of porridge and couldn't help but burst into tears. He quickly asked: "Kid, thank you so much. What's your name?" Gu Bing said, "Learn from Lei Feng and do good deeds without leaving your name!" Passers-by gave Gu Bing approving looks.

Gu Bing watched Xu Nan finish the millet porridge in one bite, and then quickly returned to work to start working, while Gu Bing worked with him to give directions to pedestrians and vehicles on the road. During the service process, Gu Bing experienced the joy and pride of helping others. Because he has contributed to society and provided convenience to others.

The cold wind was howling, but on the streets where cars and people were passing by, Xu Nan and Gu Bing's hearts were warm...
