The word "雷锋" is formed by combining the character "雷", meaning thunder, derived from an ancient pictograph of lightning, with the character "锋", meaning sharp point or vanguard, which itself is composed of the metal radical "钅" indicating hardness or sharpness and the component "夆" contributing to its pronunciation. Together, these characters create a proper noun used as a personal name, specifically referring to the historical figure Lei Feng.
