What's the song that everybody in China[supposedly] knows?
It's in mandarin though..It has somethin to do w/ everyone's name is the same because it's chinese or something xP
I just remember the words dou, mingzi, zhongguo...
My mandarin teacher said that they usually sing it during Chinese New Year's??
This is driving me crazy because Im supposed to recite/sing it/write it in 4 weeks crying
