Introduction to the Pearl Curtain and Jade Pillars: The Pearl Curtain Column slides down from the thousand-year-old boulder like a knife and axe, forming thousands of drops of water, like a hanging curtain, which is quite spectacular; the east side of the Zhu Curtain Column , the water slides down from the top of Panlong Mountain against the stone wall, forming two crystal clear streams, which look like double jade-carved pillars. This is Yuzhuji. The bead curtains and jade pillars merge into a deep pool.
