I am also a student in Jinan. . I'm in Chengdu now, and the fare for the hard sleeper is 1000. . I suggest taking a bus. I just came by bus and sat in the north area of Jinan bus station. Tickets are easy to buy. Soft sleeper . And the scenery on the way is beautiful. Get a panda card when you arrive in Chengdu. It's basically free in the urban area. Also, I don't think the itinerary is useful at all. The weather changes whenever it says, and it's far from Jinan. It's not legal. When you come to see the map, you can go directly wherever you want. .
Friendly reminder: I found that Sichuan food is really delicious these days, but it is really spicy and has a lot of oil.
For the sake of all the students, please share it with me.
