This Guizhou self-driving tour was fortunate to see China's Tianyan, which represents the intelligence and wisdom of the Chinese people and the world's leading high-tech project. We were completely attracted by its fame and decided to visit a scenic spot temporarily. And indeed, as I saw, the whole project was very shocking and proud of the Chinese. If there are any shortcomings, I think the local government may not be very aware of the value of the project and its appeal to young people who are eager to get a sense of technology, so it is not enough to promote the tourism project. And I think there should be a lecturer at the site of the visit for free to explain the tourists, so that the tourists can fully understand the ins and outs of this great project, rather than just standing on the side of the observation deck to see its size. I hope it can be improved.
