The next day: Your arrangement is reasonable. Huaxi Park and Qingyan Ancient Town are in the same direction. You have to cross the park to get to the ancient town. Although locals seldom go to the park, it is the most famous scenic spot in that place after all. The popularity itself is not very strong and the scale is very small. However, as the center of Huaxi District, coupled with its rich history, it is recommended to go in and have a look. You can choose to live in the city at night. Because Huaxi is a separate district, the main lively places are Nanming District and Yunyan District. So you have to go back to two cities from there to live. At the same time, we should arrange the trip to Huangguoshu Dragon Palace the next day as soon as possible. It is recommended to take a local one-day tour. 258/ person (including Huangguoshu, Tianxingqiao and Dragon Palace). Don't waste time at all. But a little stronger. But it's still much more convenient and time-saving than going by car. And it's really cheap. It costs 350/ person to buy tickets by yourself. So the cost performance is very high.
Day 4: You have returned to Guiyang on this day. Xingyi is still beautiful, but because there are two old people, it used to be very hard to take a bus. It takes 6 hours to drive from Guiyang to Xingyi. So I suggest you go to Nanjiang Canyon. During the day, you can call118114 to check the Nanjiang Scenic Area Management Office and ask where their cars are made. There is a shuttle bus. Very cheap. About ten dollars. It takes 1 hour to drive. You can consider staying in Nanjiang or going back to Guiyang after swimming. The tour time of Nanjiang is five hours, which is very sufficient. It's basically inexhaustible. So if you want to go back to Guiyang, time permits.
The last day is arranged according to your flight time. You can go shopping or go to Fuling Park. Personally, I don't think advertisements are interesting. Guiyang locals go because there are only two ADs in this city, and the other one is mainly for children's play. So it's actually an advertisement for adults. If you don't go, there's nowhere to go. Therefore, there are many people in Ganling AD. But there's really nothing to see.
