Project about china anyne do one? specifically chopsticks and woks???

ok so im doing a group project for my tenth grade world cultures project, and i got chinese culture so i chose my subtopic as table manners. i need an artifact or something, so im gonna write a paper about chopsticks and/or woks. i can't find enough info online about either, and i really wanna find stuff specifically about chopsicks. does anyone by chance have a report about this or find any informational websites with this info? thanks!
