There is a series called Marco polo on netflix. In one part there is a character named one hundred eyes that is suppose to be a WuDang priest. Can anyone tell if he is doing WuDang Kung Fu?

As it is a movie or television programme meant to entertain audiences, it is more than likely a fictional choreography put together for that purpose. Something akin to modern Wushu adapted for the screen. Wu Tang is not a specific system and includes a variety of different schools. Just like there is not a single "shaolin" system.

To get the first clue as to what he might be doing, read the series credits carefully to find the name of the action/fight choreographer and look up the person's background. A search on IMDB, the Internet movie database could have information.

The actor is a British-Chinese from London. He has trained in karate, Hung gar Kung fu, gymnastics and predictably, Wushu. His biography and background info is easily found online.
