I feel that sometimes driving depends on looking at the map. So I think there is no shortest, only shorter.
As for me, I recommend you to use Tencent map. As long as you enter the place you want to go, he will help you navigate in the shortest distance.
There is also a function called real-time traffic conditions, which can help query the real-time traffic information of major roads in the city, avoid congestion through driving navigation, and support as many as 18 cities.
So you can use this to get rid of traffic jams.
That's the shortest.
