You can request to take written test in Chinese. However, I doubt you can find a Chinese examiner for road test. Even there is one in the testing office, the testee is not allow to choice to prevent corruptness.
Anyway, you have to learn a few simple word for driving in order to take road test. e.g. "turn left", "turn right", "paralell parking", "change to left/right lane", "back-in", "emergent stop", etc.
