The movie titled the Sunset Street actually did exist in a rundown neighborhood in Peking, the capital of China. The street no longer existed because in the era of rapid economic expansion thanks to the reform, there was huge infrastructure constructions going on in China, and the street, and the neighborhood around it was one of early ones that were bulldozed to the ground for new construction.
The problem is that this movie made in the early era of the reform advocate the reform, but it forgets the protection of historical sites. The street itself was by no means anything historical, because it was developed in the post-revolutionary era. However, it was developed from the buildings/neighborhoods with several hundred years of history, and these adjacent buildings and neighborhoods met the same fate of the street when it was demolished. This is the fatal flaw of this supposedly good film and such ignorance about the protecting the historical sites tarnished the original good intension of advocating reform.
