Transfer bus to Ming Tombs from Badaling Great Wall

I'd like to go to Ming Tombs from Badaling Great Wall. I understand that I have to take bus 919 slow line and stop at the South Gate of The Ming Dynasty Wax Museum and then continue taking bus 314 to Chang Ling. Does bus 314 really pas this museum or I have to walk from the museum to Chang Ping bus station first before I can catch bus 314? If yes, what is the distance between the museum and Chang Ping bus station?
