You only have to translate your license into English. Then you can change it into a temparary license. I am not sure how long you can use this temparary license in your state. In PA, you can drive for one year. Then you still have to apply for the formal license by taking the test.
Of course you cannot do it by yourself. qiqigre already told you the right place you should go. I think every local notary office can do it for you, not only in Beijing.
