It's going to be difficult:) I suggest that if anyplace might have a few Greek dishes it might be Gypsies in Shekou. Directions can be found in the Restaurants tab at the top of this page. It should be in the Shekou Restaurants area of that tab. Beyond that, Hong Kong would give you a better shot of finding Greek food. Another city in Mainland China that is not too far from here is GuangZhou. That city has so many different international food restaurants. Try googling Greek Food Guangzhou and Greek Food Hong Kong. Good Luck:)
