What's the shortest way from Suining, Sichuan to Yan 'an National Road? thank you

Hello, Landlord: From Suining, Sichuan to Yan 'an National Road, if your mobile phone is a smart phone, you can download a mobile navigation, which is as clear as the friend map below, with detailed route and kilometers, speedometer and voice navigation introduction. I recommend you to use Tencent Lubao, which can calculate the time and the nearest route and update the traffic congestion at any time. Tencent map can be used for bus stops, routes, self-driving routes, ranging and so on. You can also use satellites.
