I bought a jade carving of Huanglong from Tengchong. Please help me to see what it is.

Dragon turtle, also known as "Bi xi", is an auspicious animal recorded in ancient books in China. According to legend, it is one of the "nine sons born in a dragon". As a turtle, it is a pure yang beast, which can ward off evil spirits, subdue evil spirits, dispel evil spirits, solve the difficulties of the city, and collect wealth. It is said that it evolved from Xuanwu, one of the four great beasts, and contains the book of Hutuluo, which reveals the number of heaven and earth, makes things Tai Chi, understands astronomy, understands geography and neutralizes the world. Dragon turtle is the embodiment of dragon god and spirit turtle.
