Introduction to Yarrow Garden: Located behind Taihao Mausoleum, "Yarrow Spring Bloom" is one of the eight scenic spots in Huaiyang. Legend has it that Fuxi, the ancestor of the ancestors, used the stems of this kind of grass and combined them with the texture of the white turtle's back to "draw grass and draw hexagrams", so it was called "divine grass". Its cross-section has eight ribs. This grass is found only here in the country and cannot be transplanted anywhere.
