Why did Gao De's scores drop, and so did An An and Xie Hua?

The reason why the high score is reduced, as well as that of An 'an and Xie Hua, is because of the data interoperability among the three platforms. An An and Xie Hua are both subsidiaries of Gaode. Goldtech is a leading digital map content, navigation and location service solution provider in China. Since its establishment in 2002, the company has accumulated solid technology and built a high barrier in the map industry through unremitting efforts and hard exploration. The company has made great progress in various businesses and become a leader in the industry. In addition to map navigation, Gaode Map also provides users with one-stop travel services such as taxis, hotels and tickets, saving users more than 65.438+93 billion hours of travel time every year and providing location services for more than 300,000 mobile applications.
