Actually this film was filmed in Taiwan, not China. And just to rebut a point made by the previous reviewer, there are many films that come out of China, Hong Kong, and Taiwan that are not Kung Fu films (for example all the films made by the great Taiwanese director Edward Yang).
What's good about this film is that it shows us that in any given building or city section, there's a wealth of interesting people and stories to be heard. The interconnection of these different lives seen through the perspective of Chang Chen's character (and here I agree with the previous reviewer) gives us a microcosm of life, particularly of the lower echelon of society that are trying to make ends meet, in Taipei.
Also the naturalistic acting by the characters make it all the more believable even in the face of some of the ridiculous situations that arise. A good film, gets my recommendation.
