opening times on wudang mountain

hi there. we are travelling to Wudang mountain on Sunday 28 April to climb the mountain and stay one night and then train back to Wuhan. Can someone tell me the opening times of the mountain? For example if we start climbing it at 1pm and arrive at the top by 5pm will we be able to still catch the cable car down?
Also if there is a closing time, what time does the last bus and cable car come down the mountain? Thanks!
