What are the five characteristics of Taihu Stone?

Taihu stone, also known as cave stone and rockery stone, is slowly formed after long-term erosion of limestone, including water stone and dry stone. Water stones are slowly formed in rivers and lakes by water waves and long-term erosion. Dry stone is formed by limestone in geological period under the long-term erosion of acidic red soil. Taihu stone, with different shapes and postures, can best reflect the beauty of "wrinkle, leakage, thinness and transparency". Its color is mostly white stone, and there are few green black stones and yellow stones. Especially the yellow ones are rare, so they are especially suitable for arranging tourist attractions such as parks, lawns, campuses and courtyards. It has high ornamental value.
