BF2S Forums i no at least one of the requirments for the chinese service ribbon

i was looking at my stats on bf2s and i noticed the only map i hadnt played was dalian plant. I went and played the level for 20 minutes, come back and check my stats and i have the ribbon. im not sure if their are any other requirments apart form playing every chinese map but mabey you have to be chinese for a certain amount of time as well (i have played chinese just over 10 hours). there may also be a time in thearter requirment (i have played about 20 hours on chinese maps). Any ways just thought that some people might want to know that this is probably one of the requierments. Enjoy ur gaming
