About
The Chinese word 逆鳞 is formed by combining the character 逆, which means "to go against" or "contrary", with the character 鳞, meaning "scale" (as of a fish or dragon). Together, they create a compound word that literally signifies "against the scales", referring to the direction opposite to how scales naturally lie.
