This is the Dunhuang West Line, a must-take route. Three attractions, I did not go to the film and television base, I am not interested in the humanistic landscape. In general, this place has historical significance. Tour guide, I won't say it, you will know after you report the group. The most worth seeing all day is the Yadan sunset, and the desert starry sky presented on the return trip. It is simply beautiful. It is estimated that you will not see the Milky Way several times in a lifetime. The trip was more difficult this day, the time was very long, it was already ten o'clock to return to the city, and a few group tours at noon could spell a starting point, and you must eat more at noon. Then it is best to bring 2 bottles of water by yourself, and 8 yuan for a bottle of Nongfu Spring mineral water in Yadan. The bus has a rechargeable USB and the equipment is good. Tired and happy day!
