Fire, Oracle Bone Inscriptions-shaped, is similar to a "mountain", like three (more) fiery flames on the ground. Some Oracle Bone Inscriptions simplified the flame seedlings on both sides, and wrote the main flame of fire in the shape of "human", similar to the "mountain" in seal script. Original meaning of word formation: noun, the flame produced when an object burns. The local "fire" with the character "You" in the wallboard continues the Oracle Bone Inscriptions shape. The "fire" with the word "flame" in the tripod is based on the shape of the three peaks flame, and two reference symbols are added to represent the starlight flashing around the hot flame. The word "fire" in the letter "Shu" simplifies the flame shape of three peaks into the shape of one peak in the shape of a "human", and writes the two-point symbol representing the twinkling star as "left" and "right". At this point, the font of "fire" is clearly distinguished from the font of "mountain". Seal script continues the golden glyph. When it is used as a radical in Chinese characters with upper and lower structures, "fire" is written as "quartered base"
