haha, I'm a local, I can tell you!
In Dali, painting on the walls is a tradition of the Bai people. They just like to paint on the walls of their own yards. I still appreciate it. The life of the Bai people is still very interesting. I think every household will raise flowers and paint something.
What about mushrooms? You must have seen them on the side of Chu-Da Expressway, haha. That place is called Nanhua County, which is rich in wild mushrooms, that is, mushrooms. It is called the kingdom of wild mushrooms, especially Tricholoma matsutake, which is exported a lot every year. Therefore, mushrooms are painted on the walls of villages in Nanhua for publicity.
What about dinosaurs? Haha, you must have seen something on the side of Anchu Expressway. It is Lufeng County, where one of the world's best large-scale dinosaur fossils have been unearthed. It is called the hometown of dinosaurs. Where you see painted dinosaurs, there is a large theme park called Lufeng World Dinosaur Valley, which is interesting. You can visit it next time.
That's it. Lufeng County and Nanhua County are both from Chuxiong Prefecture. I am from Chuxiong. Welcome to Chuxiong!
