Anachronistic

Yang Lu-chan trained sword forms and drills because that was the preferred weapon of the time.
If alive, would he devote practice time in the 20th Century to a 200 year old weapon that can no longer be carried on the street?
Who can say?
But it seems unlikely.

Seeking to preserve old methods, forms and drills is certainly noteworthy.
However, it is not really traditional.

Tradition dictates that you apply the art in the immediate cultural setting in which you live.
That is what Yang Lu-chan did.
