I had stayed 8 years in Nanning, be in all the time now Chengdu (already the 7th year) , so I have right to speak most.
Can say two cities are in hardware establishment respect is not a level, this need not too much quite.
The advantage of Chengdu depends on: The country locates (deputy provincial town, western rear area of city of a gleam of, country southwest) , place of scientific research courtyard is much (Cheng Fei, 29) , education is resourceful (985, 211 in all 5) , medical treatment condition is good (China on the west) , airborne traffic hub (world of non-stop flight to. Nanning relatively the advantage of Chengdu has: Coastal and open city, east mandarin of language of actor of quality of good air of environment of alliance exposition, afforest, government and colloquialism (with emigrant city close) , traffic order is good wait.
However, a city after all good, still be to depend on partly greatly very your feeling to it, what if you are in a certain place,pass is very happy, even if is a county also be indifferent to.
With respect to my individual character, I still like Nanning.
