Yu's the master of masters in Chinese sword.
I watched it on CCTV-6 around 1994. I was absolutely happy with it. Before that, I was bored by various Shaolin/Hero titled stories. The sword play in this movie is the closest match to the real : bottom line is that when one has a sword in his hand, you do not jump around and kick him. I believe it's the most practical sword play of Chinese sword. Here, I am not talking about various long knifes : Japanese swords, Chinese long knifes. They probably more practical and more powerful for real fights.
I remembered Yu forever because of that movie.
Besides fights involving swords, it have some colorful fight with long stuffs (long wide knifes like the one used by Guan Yu). The story line is fairly modern. Yu as a hero is cheated and utilized by a looking-nice king to conquer and kill, but how he wanted was peace to people. Eventually, he killed the king and hidden in "Jiang Hu".
On last word, Yu was not a champaign, he was a coach and before that he was a factory worker. Master from people. :)
