Lau Kar-Leung working on The Grand Master?

According to Sammo Hung who worked on rival Yip Man film Ip Man 2, legendary martial arts choreographer Lau Kar-Leung ("Drunken Master 2") is connected with "The Grand Master", though it's unclear in what capacity as Yuen Woo-Ping ("Crouching Tiger, Hidden Dragon") and his stunt team are also working on the film.

Heard that you sought Liu Chia Liang's counsel for this role, what suggestions did he give you?
Sammo Hung: He said, sorry, he was working on Wong Kar Wai's The Great Master, and had to keep his own counsel, so, I had to do my own homework.
