I've seen this when I was a little kid and I've been looking for it for a very long time. It's an old Chinese kung fu movie probably made around the 70s or 80s. All I can remember from the story is that a young man comes home to find out that his house has been ransacked and his mother was killed. So he trains kung fu to seek revenge. When he got really good at kung fu, he fights with the men who killed his mother and won.

I was only 6-7 yrs old when I've seen this so the memory's kinda messed up now. But I remember that there were a lot of huge clay jars filled with water.

I know the plot sounds so generic, that's why I've been having a really hard time looking for it. But I'd really appreciate if someone could help.
