:(

I'v try to search it. But I failed.

Yes! I've watched 《流浪北京》 and it was very, very interesting; that's exactly why I want to watch 四海为家.. :)

I know it's hard to find, but I also know people who have watched so it's not impossible. I'll keep searching :)

It is very difficult to find even for Chinese. It is said that only 吴文光 keep it...I helped to search it online, and apparently no result:( Have you watched his another film called《流浪北京》？
