First of all, Chengdu-Lijiang, you are missing an important node, Panzhihua.
I stayed in Chengdu for a day or two, went to Panzhihua by train, stayed in Panzhihua that night, recommended the absolutely best restaurant "Liyuan Xiang" in Panzhihua, and tasted pickles, which was very distinctive. Stay at the best Chuanhui Hotel in Panzhihua, with four-star housing and Ctrip reservation, 100 for one night. The next day, Panzhihua-Lijiang, about 6 hours, by the Jinsha River, the scenery is absolutely invincible. Highway 20 12 will be opened soon, and there will be no such blessing then. You can choose to stay in Lijiang that night. When you get out of the bus station, walk across the road on your left. There are two good hotels. I went to Shuhe ancient town the next day (suggested, because I personally think Shuhe feels particularly good, and Dayan's business atmosphere is too strong). I stayed at Happy Hour Inn for 70 nights, and the boss was very nice. It should be more cost-effective Let's stay for three days, that is, in the compound. Shangri-la is nothing, just watch the tiger jump or the tiger jump along the way, Tibetan areas. You arrange it yourself. Then from Dali and Kunming to Dali, please take a bus instead of a train. Living in an ancient city in Dali is not recommended. Although there are good ones, don't publicize them at that time, just ask me again. Stay three days. During this period, I will go to Yiheng Hotel and eat with Cangerchun. Sauce snail meat or something. It is also a kind of rest. Look at Cangshan Lake and Erhai Lake. You can arrange it yourself. Banna is in the south. I haven't been there. I won't talk nonsense, but it is said that Ruili is good. There is nothing to play in Kunming. Eating rice noodles across the bridge, Xiang Qiao Garden or building a new garden are all good. Then you can check again. I don't remember clearly if there are any problems.
By the way, Lijiang black goat must be recommended. There is a street that recommends Ashou black goat (because I have been there, it is great). Absolutely delicious.

Or the itinerary is in doubt, anything will do. Besides the three northeastern provinces and Fujian, I have been to Chinese mainland.
