I would like to know if there is a bus transfer from Xingping to Yuanshuo then if the area for the ship is better between Yangdi and Xingping.

Yes, there is and the scenery between Yangdi and Xingping is the best section of Li River Cruise. After getting off the ship at Xingping, you need to take a battery car or van or motorcycle to local bus station. There you can take a direct bus to YS. If you refer to the bus ticket reservation, no need to book in advance at all!
