Is there any cheap accommodation near Longdongbao Airport in Guiyang?

Yes, a lot. Longdongbao Street to Xiaobi Township is 20 to 50 yuan, but the environment is relatively poor. Even if you walk from those places to the airport, it will take about half an hour, and it will not take more than ten minutes by taxi. Getting on the plane is a little more troublesome than taking the train, mainly because the security check is too time-consuming, and it doesn't take a while to change the boarding pass to check the luggage. If you are flying for the first time, you'd better enter the airport about 1 hour in advance. At that time, most of the passengers who caught that flight were there, so you can follow others. Be careful not to bring inflammable and explosive articles, including mineral water and drinks.
