Excuse me, which bone of the stone belongs to the pig?

Xi Shigu, also known as Xi Gu Fei, is often called in South China, Hong Kong and Taiwan. It's actually a pig's scapula.

Shoulder blades are also called shoulder blades and pipa. Located at the back of the chest, it is a triangular flat bone between the second and seventh ribs. Divided into two sides, three corners and three sides. The subscapular fossa is a large and shallow fossa in front.
