The Last Emperor from Lu Chen has been one of my favorites.
just watched it, it is a pity that the video quality of performances of that time is sooo bad... and it composer is also Japanese -- Ryuichi Sakamoto (I know him more than Shigeru Umebayashi)
Shigeru Umebayashi is also the composer for Onmyōji (Yuzuru's Seimei free). I found out last year when a Korean lady skater Na-Hyun KIM skated to House of Flying Dragon, I was like, this music style is so similar to Seimei, and it is indeed from the same composer.
Speaking of house of Flying Dragon, I don't really care about the plot, but the Chinese classical dance in it is really iconic in Cinematography.
the dance from the movie

Korean skater Na-Hyun KIM's free House of Flying Daggers (this performances was a little sensation among Chinese figure skating fans back then because of the Chinese themed music)
