Dear, for your smooth journey, I suggest you use Tencent map. The revised Tencent map is very good. Support the whole process of networking, offline download mode is completely zero traffic. When you need to slow down, it will also display traffic lights. There are voice prompts. You can also use Tencent map to find a lot of useful information for you, such as where you want to go but don't know how to get there and how far it is. Ok, now Tencent map comes in handy. You can use Tencent map to find the place you want to go. Just enter your place name at the beginning, and the nearest route will come out at last. There are also functions such as positioning, checking the surrounding group purchase information, real-time road conditions, weather, ranging, street view and so on.
