Chinese waxwood is a tough thing to get info about. One of the common chinese names I found is Bai La Gan. No luck on the botanical name.
Here's something from a martial arts site
The first weapon in the Fei Lung Fu Mun is the pole. We refer to it as the "Cern Gup Dan Gwun" (Single end staff, where both ends are used). The weapon varies in length with the height of the user, and it is properly measured by standing straight and extending your arm. The pole should be the length of the outstretched arm. The wood is the common Ba La White waxwood that is typically from Shangtung, and common in martial arts circles. We specially treat the pole by immersing them in Tung oil for a period of six months so that the pole remains flexible and virtually indestructible. A good Ba La Gwun is considered to obey the user's commands.
So you might think about soaking a willow or hazel pole in some tung oil and see what comes of that. I'm not sure how white anything would be after being saturated in tung oil, but that's what the man says
All the best,
