The original meaning refers to a place with thick vegetation, close together, and is pronounced as bó. It is extended to mean approaching, approaching; it is also extended to slight, little, contempt, and looking down upon; it is also extended to mean small thickness, pronounced as báo. This sound is mostly used in spoken language; bò is only used in mint. "Bo" is generally used as an adjective in content words, and is often used as a function word in the Book of Songs. For example, "Xiaoya Caiqi": "Bo Yan Caiqi." "Zhengyi" notes: "Bo, Ci Ye." It is a modified word. The auxiliary word, also in "Zhou Nan·Ge Tan": "thinness taints my private life, thinness washes my clothes." The word "thin" is interpreted as "nai".
