Only after checking did I realize that Gaode is used by 800 million people every month, maintaining over 5 million kilometers of roads, with Alibaba investing tens of billions every year behind it. Electronic eyes, construction information, traffic light countdowns, lane reminders, villages have it, cities have it, even the small roads within the Fifth Ring are updated almost every month. In the unmanned areas of Tibet, Gaode can help you find gas stations, considered a "lifesaver" by netizens. The app appears to be free, but underneath it is technology and data, with countless engineers continuously outputting. It’s not just navigation, it’s a long-term money-burning, yet essential infrastructure. Will you use Gaode or Baidu?
