Bai Yuncen, how can I tell, through all these clouds?. What does this poem mean?

The whole poem is as follows:

Visit Baiyun Mountain

Song Yuan Tang

Cure Zhang Baiyun Cen, how can I tell, through all these clouds?. I suddenly saw the king in the cloud and lived in Baiyun Township. Raise your hand to make a bamboo cloud and recruit me to climb the cloud road.

it's a long way to go, and I'd like to ride the yellow crane. Yellow cranes never return, and white clouds come and go.

cen, a high and steep mountain.

Ce Zhang Bai Yuncen, how can I tell, through all these clouds?. Climbed the dangerous peak covered with white clouds with a cane, and was in the clouds without knowing where he was.
