Traffic in Nanning is a conglomeration of buses, cars, bicycles, motorcyles, mopeds, etc. The fact that we only saw one accident during our stay there blows my mind. Maybe we have too many road rules in the U.S. Naaahhhh.
By the way, the guide said in the summer the typical work day includes a 3 hour break mid-day because of the heat. Many workers use this time for a nap. So I guess that adds 2 extra rush hours a day. Probably worth it for the siesta.
