Chengdu-Ya 'an-Yingjing-Hanyuan-Shimian-Mianning-Xichang Chengdu-Ya 'an is full-speed, with good road conditions. It is 122km from Ya 'an to Hanyuan, and the road surface is good, but there may be snow on the mountain, so it is recommended to bring your own snow chains and anti-freezing equipment. Hanyuan to Shimian is 78 kilometers, and the road surface is good; Asbestos is 118 kilometers to Mianning, which takes about three hours. On the way, it will cross Tuowu Mountain, and it is not easy to walk for 1 kilometers. It's 7km from Xichang to Lugu Lake. It's suggested that you stay in Lugu Lake (Sichuan) for the next day and go to Lugu Lake (Yunnan) for a look. If you have time, you can go from Lugu Lake to Gesala in Panzhihua and then take the expressway from Panzhihua to Xichang and then go back to Chengdu. I think you should probably go to Torch Festival next month. 1. Try to choose tourist attractions along the expressway to reduce the chances of vehicles passing through villages and towns. Walking without viewing, viewing without walking. 2. Avoid long-distance cycling and leaving it in the wild. Take a box of pure water, which can be drunk or added to the water tank. 4. Prepare a clean rag. The temperature difference inside and outside the carriage will make the side window full of water vapor, which needs to be wiped frequently. 5. Oil, coolant and glass water should be checked by opening the machine cover every morning. 6. Don't wait for the oil shortage indicator to light up before looking for a gas station. When you see a good gas station, you can refuel at any time. 7. If the car breaks down on the mountain road, it should be repaired by the roadside where both sides can easily find it, and warning signs should be set up. 8. If a family of three goes out, children should sit in the back row and fasten their seat belts. List of equipment: 1. A set of vehicle tools, a fully inflated spare tire wrench, a fire extinguisher, a tow rope, a large line for starting, a stop warning sign, engine oil, gear oil, brake oil, spare light bulbs, some safety tubes, a box of purified water, a thick wooden block and a worn coat, a pair of engineers' shovels, a clean rag, a nice CD and a big bag of snacks. 2.
