In the word-making era, the source of water flow was called "spring"; The mountain spring splashed on the stone wall is called "water"; The water formed by mountain springs is called "Jian"; The clear stream formed by mountain streams on the ground is called "stream"; The water flow formed by many streams is called "chuan"; The big river formed by many rivers is called Jiang, and the largest river is called Jiang. Oracle Bone Inscriptions looks like liquid flowing downwards, splashing on both sides of the rugged rock wall. Mun-song Kim continued the Oracle Bone Inscriptions glyph. Some inscriptions dilute the rugged image of the rock wall in the Oracle Bone Inscriptions glyph into a flowing curve. Seal script continues the golden glyph. The official script has a large deformation, so the dotted line representing the rock wall in the seal script is simplified to a vertical line, and the four drops of the seal script are written together, and the pictographic characteristics of the spring flow disappear. In Oracle Bone Inscriptions, dynamic flowing water is generally written as vertical or, while static or overflowing water is generally written as horizontal.
