One strategy in using GPS location in China is to use the Google GPS to approximate the area, then ask the person their actual geographic location, and use Google.cn/maps to find their Chinese GPS coordinates. Google.cn does comply with Chinese laws and uses the GCJ-02. The Chinese GPS coordinates are good for Google and Bing maps, but not Baidu.
