In the Song Dynasty, there was a needle shop named Liu in Jinan, Shandong Province. This family specialized in making fine needles for kung fu. Because there was a stone rabbit at the door, the needle shop took "White Rabbit" as the mark of its goods, printed the pattern of the rabbit on the wrapping paper of the needle, and wrote the words "Rabbit as a souvenir". Whether this kind of "White Rabbit" brand fine needle was a famous brand at that time could not be verified, but it can be believed that the rabbit pattern must have brought many buyers to Liu's family.
