According to some scholars, this form is called a xi.  This Qing dynasty version is based on jades from the Spring and Autumn period. During that period, these pieces were used for taking out knots in ropes and became a gift of filial piety, whereby children would give these jades to their parents as a symbol that there would be no disagreements between them.  See an Eastern Zhou Dynasty xi in the British Museum with a hooked tail, illustrated in Jessica Rawson, Chinese Jades, British Museum, London, 1995, cat. no. 17:11.
