“Leng” is a part of the pork spinal bones, with a bit of meat attached to the bone. The Chinese word ‘Leng’ means dragon, short for ‘Ye Leng’, meaning dragon spine. This menu is not made from dragons in any way. But when using the word Ye leng, it is because when the vertebrae of a pig are dissected, the ribs are completely taken out, leaving only the long spine from the neck to the base of the tail which is shaped like the bones of a large snake or dragon.So Chinese people call it dragon bone or Ye leng
‘Leng’ has been shortened from ‘Ye Leng’ a Chinese word meaning dragon spine, but the word actually refers to the spine of a pig. When the vertebrae are removed and all that is left is the backbone and attached meat, it somewhat resembles a dragon’s spine. Leng has always been used in soups as it is a very cheap cut of meat and imparts a sweet, mellow flavor. It was originally served as an accompaniment to chicken rice dishes or noodle soup but some diners enjoyed it so much that chefs decided to spice up the soup and sell it as a dish of its own. ‘Leng Zab’, a version featuring lime and handfuls of chilis is currently enjoying great popularity with spice lovers.
