Nostalgia originally had only one kind, that is, when someone is in a place B and misses his hometown A. Yu Guangzhong's poem "Nostalgia" is. Now there is another kind of feeling, which is the feeling of sadness that arises when someone stands in a place and misses what happened here several years ago. "The Piano of Steel" is it. The former is nostalgia within a regional scope, and the latter is nostalgia within a time scope. The expression method of regional nostalgia is generally to overlay the lives of places A and B separated by time and space, which will produce a sensational contrasting effect. As long as temporal nostalgia intersperses life in the same place in different eras like a montage, the tragedy will reach a climax.

But Zhang Meng's "The Piano of Steel" can express the overwhelming nostalgia without flashing back to the sunny days in the past. This skill is at the master level. And Zhang Meng is obviously not a master. Before this, this Northeastern man who was born in the mid-1970s was unfamiliar to many people. I, too, have never heard of his name. This is not surprising, because he has only directed two films. In addition to this one, there is also one called "Blessed with Big Ears". I don't know what the artistic level of "Blessed with Big Ears" is. But this "Piano" can compete with the world's first-class films. Based on my memory, it should be the best domestic movie in the past five years. With it, Chinese movies seem to be saved.
