The kanji 充 is a phono-semantic compound (形声文字). The left side is a part related to "person" or "human" (usually related to the "person" radical, which is ⺅). The right side is pronounced "jin" and originally represented a container filled with water or other items. This kanji evolved to show filling or completeness, combining the idea of something being contained with the sense of fullness.
