Help the road conditions from Panzhihua to Lijiang

I just passed 10. 1 this year. Panzhihua to Lijiang takes the road from the west to Huaping County, mainly in factories and mines. This is very bad, mainly gravel and tunnels. It's raining and muddy, and it's dusty on sunny days. After Huaping County, the road conditions to Yongsheng County are slightly better and the road surface is relatively flat. It's Panshan Highway, with many bends, and cars with too small displacement (below 1.5) will be very hard. We leave Panzhihua at 8: 00 in the morning and arrive in Lijiang at 6: 00 in the afternoon. Basically, we want to stay in an inn in Lijiang ancient town. It's best to book online for holidays in case there is no room to stay. From Lijiang to Dali, don't take Jianchuan National Road (navigation seems to prefer this route), because Lijiang is very narrow and easy to get stuck in traffic, so take Heqing County instead. There is a section of airport expressway, which is easy to walk. After Heqing, it is a secondary road in go to dali, and the road conditions are OK. Dali to Kunming is the whole expressway.
