Introduction to Chashan Suwu: Chashan is located behind Foding Mountain, winding from north to west. Every time before sunrise, the tea forest is shrouded in mist, sometimes like silk threads, sometimes filled with mist. The tea from Putuo Tea Mountain is called "Yunwu Buddha Tea" because the tea trees are mostly planted by monks, so the mountain monks' talk about "Tea Mountain Suwu" has a unique charm.
