In ancient times, the classification mentioned red jade, white as fat-cut, yellow as steamed chestnut, black as lacquer, and red as cockscomb. Refers to the top grade in jade. There is an old jargon in Wanyu, "one red, two yellow, three ink, four sheep fat". Red jade is a gem of Hetian jade, but like the dragon stone species in jade, it basically only exists in legends.
