Introduction to Yao Guanding: There are two Yao Guanding in Beitianmen of Mount Tai; East Yao Guanding and Xiyao Guanding. Legend has it that Emperor Yao came here in ancient times to watch the sunrise from the top of Dongyao Temple and watch the sunset from Xiyao Temple. Climb to the top of Yaoguan and look far into the distance. The top is a purple sky, and the sun is still sleeping. There is already a red light in the sky, and the faint clouds in the sky, illuminated by the rays of the sun, are like a gauze, floating gently in the sky.
