Lu Guang

Someone who would repeatedly break his own rules about time travelling just to save the one he loves and cares about most; a guy with white hair that has powers of time travelling

Lu Guang is one of the main characters in the donghua (Chinese animated show) Link Click, or otherwise known as Shiguang Daili Ren, and has supernatural powers that allow him to peer into photographs and retrieve information, but can possibly have other powers too...
