"Yingbin Bone", also known as "Yingbin Bone Powder", is a common folk banquet product, which is mainly used to show the welcome and respect for both the host and the guest. Welcome bones are generally made of cow bones or sheep bones, which are conical, small at the bottom and wide at the top, and generally decorated with red silk thread or ribbon at the top. It is said that the origin of the welcome bone can be traced back to the Han Dynasty, when it was carved with ivory and used for banquets, and then it gradually evolved into a welcome bone made of cow bones or sheep bones.

At a banquet, the host usually calls the roll and passes it on to the guests. After receiving the greeting guests, guests usually say some self-introduction words to show their respect for the host and other guests. When using the welcome bone, it should be noted that after receiving the bone, it should not be placed on the table, but should be inserted into the mixing spoon of the cup or held in the hand to show respect and courtesy.

Bone-topping guest is not only a banquet project, but also has profound cultural connotation. In the ancient traditional culture of China, welcoming guests is symbolic, representing "backbone" and "courtesy". It symbolizes that people should maintain good moral habits, pay attention to etiquette when interacting with others, and pursue honest and harmonious interpersonal relationships. In modern society, although welcoming guests is not as widely used as in ancient times, the humanistic spirit behind it is still worth inheriting and carrying forward.
