The key is to look at your household registration, because the theoretical examination of teacher qualification certificate is organized by provinces. If your household registration is in Liaoning province, you can register for the exam in Shenyang. If you don't, or only when you are in school, I suggest that you don't take the exam, because you must go back to the education bureau where your household registration is located to qualify, and the results across provinces will not be recognized.

If you are registered in Liaoning and don't attend the training course, you should pay close attention to the announcement on the official website of Shenyang Education Bureau, which will tell you the address and time of registration.
