After few month of work, most roads, streets, forest, airports, golfs and football pitch are done, still lot of tennis/basket pitch, farm fields, service road, and residential roads to do. There are also lot of street and bus stop to name. Only few buildings are drawed among ten of thousands. About Six month ago, there was only about ten roads, mostly not really well placed due to GPS errors. http://osm.org/go/41XJPhb-
This is another chinese city I mostlycartographied big part, after :
Weihai municipality, Shandong province (山东省威海市) http://osm.org/go/5zmnH1a--
Jingzhou municipality, Hubei province (湖北省荆州市) http://osm.org/go/5O_krIm
big part of Huzhou municipality，Zhejiang province(浙江省湖州市), and most of it's famous chinese brush manufacturer village，Shanlian (善琏镇) http://osm.org/go/5mfE4uQW
Big part of Qingdao and most of the actual drawing of Yantai, Penglai, Wendeng， Zhaoyuan and some other city of Shandong province (山东省青岛市,烟台市，蓬莱市，文登市，招远市。。。) http://osm.org/go/5zkCAH--
I trace street and road using statellites and planes pictures as Yahoo or Bing, GPS trace are really often very bad, because car has to stop, cross other cars, and are really less precise than actual plane pictures.
Perhaps need to document how to cartography China, with it's special roads sign, as bus stop, road parrallel paths, mostly used by bikes, bicycle of for going inside residential roads, turn back path. The road signs for highways, street roads, bicycle way are is moslty like in France, so it should not be too hard to cartography for European OSMers.
I tried to work as good as possible on Airports runways, taxiways, aprons and building, in the hope to use them in Flightgear flight simulator free and opensource software. In this software, there are only few airport in for China, and mostly represented by only a runway (where there are several runway) and sometime wrongly placed taxiway, like Shanghai Hongqiao airport (I don't worked on it on OSM) (ICAO:ZSSS) http://osm.org/go/5ngxf~p
