Practice writing Chinese

when i was younger i wrote letters in chinese to my grandmother and in the beginning of high school i wrote to my cousins. my parents are both from china and my dad came to seattle to get his masters, and that is where i was born. since birth they have always spoken to me in chinese so i understand it fully. i can talk to people but the only thing im at a disadvantage is writing and reading it. i went to a chinese school since i was six up to the eighth grade, but because other things started taking up my time, my knowledge was being shredded into really basic forms. hopefully i can hold onto what i have and build it instead of simplify it.
