An attractive young lady walks through a crowded marketplace and meets the eyes of a young grocer. They continue to smile and stare at each other as she continues walking, and he jumps from venue to venue, trying not to lose sight of her in between all of the obstacles. But, neglecting his blind spot, he suddenly crashes into a bicyclist pulling a large load of weight and all that is knocked down creates a collapsing domino effect throughout the entire marketplace. The young grocer ends up in the hospital and surprise– his doctor turns out to be the young woman he met earlier.

I can’t figure out the song though; it sounds like a girl is singing "children in a ring" — might be a Chinese translation of the "ring around the rosy" song?
