The kanji 流流 is a pictograph and ideogram. It originally depicted water (represented by the three strokes on the left, resembling the character for water: 氵, a simplified form of 水) flowing down a channel. The right side represents something being carried along or drifting. Over time, the character evolved to represent the broader concept of flowing, encompassing both the physical movement of water and the metaphorical sense of movement or progression.
