Beautiful cleaner - better than glamorous car models at the Beijing Auto Show

The whole scene has more than one female cleaner in red. There is another one in the distance in the picture. The woman cleaner in the picture is carefully polishing the car tires. I don't know why, but there is a hint of sadness between the eyebrows of the younger sister in red in the picture. It is perhaps this kind of sadness that moved me. And the story that happened next made me, a battle-hardened old man, shed tears!
