walking stick sword

I have this brass cane with a sword it has Chinese emblems on it. Can anyone id it for me, it has a dragon running down the length of the cane and appears to be hand made old brass its extremely faded.

the inside of the brass cane has a wooden insert to allow the sword to slide inside it. The brass cane appears to be welded at the join that runs the entire length of the cane the weld appears to be brass as-well. The dragon wraps around the entire length of the cane. the hilt appears to have a crest on the top but unable to be seen properly.

The blade is long and ends with a triangular point however is to rusty to see any marks on it.
