1. Bo (pinyin: bó) is a general standard second-level Chinese character in Chinese. This word first appeared in oracle bone inscriptions in the Shang Dynasty. The ancient character shape is Congbai, Congjin, and Bai also represents the pronunciation. Its original meaning refers to a kind of white silk fabric, and later it was used as a general name for silk fabrics. They are often used as place names in oracle bone inscriptions.

2. The word "帛" was first seen in oracle bone inscriptions, and it still maintains its original structure after several generations, from "white" to "scarf". The physical structure of bronze inscriptions is exactly the same as that of oracle bone inscriptions. Xiaozhuan is the same, but the strokes are more regular. Official script follows the physical structure of Xiaozhuan. "Shuowen Jiezi·Jinbu": "Bo, Zeng. Congjin, white sound." Xu Shen believes that "Bo" is a pictophonetic character, while some people think that "白" not only expresses sound, but also expresses meaning. Therefore, the original meaning of "帛" refers to "white silk". Duan Yucai's "Shuowen Jie Zi Annotation": "Silk, today's Bi Se Zun." The so-called Bi Se Zun is white Zeng, that is, white silk. It can be seen that "白" in the word "帛" not only expresses the sound, but also expresses the color of the silk. The word "帛" comes from "jin", and "jin" means to wear a towel. "Jin" and "白" form "帛", which means: a scarf made of white silk fabric. The characters "白", "Jin" and "帛" are all found in oracle bone inscriptions. This fact shows that the sericulture and silk weaving industries have appeared at least in the late Shang Dynasty.
