How many hours does it take to drive from Chengdu to Lugu Lake?

Hello, I just drove from Chengdu to Lugu Lake in May. The total time without overspeed is about 12 hours. The approximate time is as follows: it takes about 2 hours from Chengdu to Ya 'an, 1 1 o'clock to have lunch in Ya 'an, and then take Yaxi Expressway. The tunnel of Yaxi Expressway is generally limited to 60-80 years, plus parking and sightseeing along the way, so I walked more than 200 kilometers to Xichang for 4 hours. Stay in Xichang, and then go to Qionghai. The next day, I arrived at Lugu Lake and basically walked the whole mountain road. It took about 3 hours from Xichang to Yanyuan County, and about 3 hours from Yanyuan to Lugu Lake at noon. You can ask questions and hope to adopt them.
