I have been in Nanchang for a year now,I believe that all students knows about the traffic here! Whenever we step out of the school,every students must be excited.some people have low quality,they would cross red light and jump over fences.Even drivers pass red light,retrograde and so on.Traffic lights are not perfect.there are times when green light and red light show at the same time,and also sometimes there are no yellow light in various locations. If we need to change the traffic for Nanchang,we must be good ourselves.We will not pass red light,and will not jump over fences or crossing the road.
