This username combines two cultural references. 'Crayon' sounds like a character in the popular Japanese manga 'Cr<NAME>' (whose main character's English name is usually translated as 'Nobita'), which most children are familiar with; 'Little Xin loves Crayola (brand name for crayons) accompanying little Xin forever'. It seems fun and full of nostalgia.
