I want to join Xi 'an's donkey friends group. Where can I sign up?

I tell you about a group of donkey friends who run around the world. Their leader is still good. In addition, the departure place of most tour groups is at the east gate of the provincial stadium. If it's convenient for you on Saturday, you can go to see if there is anything that meets your requirements at six or seven in the morning, but the average airborne person will pay more and it's not expensive.
