The plot of the film is not ups and downs, and it is thrilling and tells such a story.

In a high-rise block, there is a lame old beggar, leaning against a pillar, standing on the side of the road begging every day. His hair is unkempt and his expression is dull. He always stared at a pair of sunken eyes, silently watching the passing pedestrians. He has a deformed paper cup in his hand. Among pedestrians in a hurry, there are often good people who stop to take out change and put it in paper cups. He never begged for charity, never thanked the kind people who gave charity, and didn't even show a humble smile.

There is a successful man who owns his own company, luxurious office and high-end car. Every day when he passes by the beggar after work, he will take out a change and throw it into the beggar's paper cup. This has become a common practice. The beggar noticed that the successful people's cars had to be parked in the open air in the nearby open space because the underground garage was not repaired. Perhaps to thank the benefactor who gives him alms every day, he silently cleans the car for this benefactor. All this was seen by successful people through French windows. I don't know if I can't bear it, or if I'm afraid the beggar will stick with him, or if I don't want to owe this poor disgusting person a favor. When I passed the beggar after work, he put a coin into the paper cup as usual and said maliciously to the beggar, this money is for you, not for cleaning the car. Please don't touch my car in the future! Without saying anything, the beggar stubbornly washed the car for the benefactor the next day.

Therefore, successful people still give beggars change every day, and beggars clean their cars every day. This seems to be a compulsory course in two people's lives. In their spare time, successful people will stand in front of floor-to-ceiling windows with high-powered binoculars and watch beggars clean their cars. The beggar in the camera washes the car very hard and doesn't even let go of anything in the mirror.

However, one day, when a successful person took out his wallet after work to give a beggar change, he found that there was no change. He felt as if he owed money to a beggar and could not walk in front of him. However, the successful people who tried to escape by relying on the bodies of pedestrians were found by beggars. He uncharacteristically chased up with a paper cup. Successful people got angry and drove away. Although I saw the beggar fall to the ground in the mirror, I didn't even loosen the throttle.

For several days, the successful man's car was not cleaned, and his car was covered with dust. I never see beggars again before I get off work every day. One day after work, he couldn't hold back any longer and drove through the streets to find the beggar. Finally, in a downtown area, he saw the familiar figure. When he greeted him with a big bill, the beggar glanced at the bill in his hand coldly, turned his back arrogantly and walked away.
