I'm from gedian, too. I just made it today. Looking for it for a long time, the number displayed on the internet has been disconnected, and there are problems with the address of online registration. It's one or two hundred meters to the left opposite Egao, belonging to the Municipal Civil Service Bureau, first floor 103. After getting off from gedian to Sun Yicheng, you can go straight, take the No.7 bus, or take a taxi to Sun Yicheng directly. Egao should almost know how to find it. Just bring your registration card, and you don't have to pay.
