where can I take direct bus from three kingdoms City to lingshan? what is bus number?

There is no direct bus to Lingshan, you need to transfer once in the midway.
Take sightseeing bus line 1 near the ticket office of the Three Kingdoms City for 3 stops to Meiyuan first, change to bus 88 or 89 to Bibo Shanzhuang, then walk northwards for 350 yards to find the entrance of Lingshan.

thank you
