As soon as we arrived at the Xilai Passenger Station, we saw the big words "Xilai Ancient Town" on the red archway. Hey, another built ancient town, let's be a little disappointed. But now let's take a look. Xilai is a small town in Pingba Mountain. It has grey houses, slate pavement, ancient streets and ancient towns scattered all over Sichuan. But it is worth mentioning that Wenfeng Pagoda, boat coffin and more than a dozen ancient banyan trees along Linxi River in the old streets confirm the history of the ancient town. Although there are many folk houses in Western Sichuan in the Ming and Qing Dynasties, which have a long history. But that is more than a hundred years of history, thousands of years apart from those ancient banyan trees and once this land, there should be little left.
