The community located in Baoshan District, but Baidu online map shows it in Pudong New Area. Customers keep from reaching the destination according to the wrong information. Recently, Miss Yan who lives in Sanyou Xiandai Cheng on Yunxi Road of Baoshan District felt confused that the online map was too inaccurate, which made her friends totally lose their direction. After investigation, I found that due to the lack of community names on the map, many people like to check the community address through the online map, but because of the inaccurate information, citizens are easily misled when they query.
