没有保护色就是一个枯叶碟

This nickname draws inspiration from nature. In Chinese culture, people often use natural elements to describe a longing for harmony with the surroundings or unobtrusiveness. 'Mo fei bao hu se jiu shi yi ge ku ye die' can be translated as 'Without protective coloration, it is just a withered leaf butterfly'. The withered leaf butterfly (Kallima inachus) is a species famous for its camouflage ability, which blends itself seamlessly among dry leaves to avoid being preyed upon. So this nickname might suggest someone who desires a quiet existence without attracting too much attention, hoping to blend in with the environment.
