Is it easy to ride from Chengdu to Xi 'an 108 National Road?

① It is possible to go to Xi 'an by bike along 108 National Road, but it can't be said that it is easy, because it takes a lot of effort to cross the Qinling Mountains. ② There are many intersections between 108 National Road in Guangyuan City and Guang Bei section of Beijing-Kunming Expressway through Chaotian to the junction of Sichuan and Shaanxi (Qipanguan), but it does not affect the traffic of 108 National Road, so you can ride and walk from Chaotian to Ningqiang; If you really want to ride a bike from Chengdu to Xi, please pay more attention to the weather forecast. It is very dangerous to encounter heavy rain and mudslides.
