On the west side of the airport, at the southern end of the freight road, get off the expressway and go straight along Yingbin Avenue of the airport. See the sign of China Southern Airlines on the right side of the road, and the next intersection is Freight Road. Turn right. When you come to the southern end of the freight road, there is a small sign of China Southern Airlines. According to the sign, the business hall of China Southern Freight Department is at the end. I have just been there, and I should check in my pets (solo) there. If the random consignment of pets should be handled at the airport, you'd better.
