An outpost makes inroads

The settlement of 2,000 inhabitants is essentially designed for ancient urban warfare.

One alley hosts an old opium shop. Buyers would stand in the street and the vender would hand purchases over a counter. There was a hole in the wall behind where the buyer would stand, through which an armed person would supposedly use weapons to force the buyer to pay if they refused.

Nearby Yunshan village is built in a valley.

It was not only a defense outpost but also a trade hub for military supplies.

Today, the tourism area attracts young artists from near and far, who paint its views.

An Anshun University instructor surnamed Zhou says he brings his students to the area to paint for about two weeks every year.

"We come for the spectacular architecture and local customs. It's not crowded with visitors. We enjoy the tranquility."

Benzhai's Party chief, Mei De'an, says the challenge is to attract more tourists who stay longer.

Yunfeng Tunpu is a national AAAA site. (AAAAA is the highest ranking.)

"Infrastructure, service and management are vital. That's what we're working on," he says.

Mei initiated protection of the ancient houses in the 1980s, despite some locals' objections.

The government there built a new village for inhabitants in 2007, and many people moved into modern homes.
