Chinese Book, Bullied Girl

there's this book i read back in elementary school (2005-2011) where this chinese girl (6-10) was bullied by her "friends". the illustrations were those sketchy black and white drawings that scattered the pages. the only real colors were red for the cherry blossoms, and i believe she had a yellow raincoat, but don't quote me on that. there's one part i remember with the illustration as a classroom, and she was alone. it was quite sad. i just really wanna find it and read it again. thanks!!!
Could it be In the Year of the Boar and Jackie Robinson?
