The study of the old Guangtu has been closed, and the study of the new Guangtu has been opened. If you want to apply for a permit, you have to bring your ID card. It seems that you have to pay 5 yuan, and it is closed every Wednesday. You can check the details in their official website.
If you live in a city, I suggest you go to the central map. After all, the new Guangzhou map is inconvenient and noisy.
