Preparing to go to Dunhuang from Chengdu, please provide a self-guided tour guide!

You can take the train from Chengdu to Lanzhou. There are 2 trains with good timings: K856 (departs at 3:30 pm, arriving in Lanzhou at 12 noon the next day) and T22 (departs at 9 pm, the second train Arrive in Lanzhou at 13:20 noon the next day), buy the train ticket K9667 (17:56-8:20 the next morning), you can have a bowl of Lanzhou Ramen during the few hours you are in Lanzhou, and go to the Yellow River to see the Zhongshan Bridge. Statue of the Yellow River Mother, sitting on a sheepskin raft. The train departs in the evening. To Dunhuang, there is a small green bus next to the train station. It says urban area - railway station - Mogao Grottoes. They run every 30 minutes and leave at the hour and half hour. It takes 3 people from the train station to the urban area. Yuan, the train station is 13 kilometers away from the city, and it takes about 10 minutes to reach the city. Find a place to stay. There are many hotels and guest houses in Dunhuang city. Then try to set off at 10 o'clock to go to the Mogao Grottoes. It is still the small green bus. It is 8 yuan per person from the city to the Mogao Grottoes. It is 25 kilometers away from the city and can be reached in 30 minutes. Before April 31st, the Mogao Grottoes are off-season. , tickets are 80 yuan (including guide). It usually takes 2-3 hours to visit and return to the city. Take bus No. 3 to Mingshashan Park (6 kilometers away from the city). The ticket is 120 yuan and the fare is 1 yuan per person. You can play in this park until about 8:00 pm. Bus No. 3** *The last bus back to the city is at 8:00. Then go to Shazhou Night Market to eat. Apricot skin water and donkey meat yellow noodles are famous local snacks. The next day, we chartered a car to go to Yadan Landform, Han Dynasty Great Wall Ruins, Sunshine, and Yumenguan Ruins. The charter fee should be controlled at around 400 yuan. The tickets for each scenic spot are tens of yuan. The round trip on the same day is about 400 kilometers. Get some rest at night. Return to Lanzhou the next day and return to Chengdu from Lanzhou. I just traveled through Gansu a few days ago. I feel that if you only visit Dunhuang, staying in Dunhuang for 2 days is enough. When you return to Lanzhou, if you have enough time, you can visit Jiayuguan and Wuwei. Hope it helps.
