Besides, he also plans to set up a big stage for musicians to hold gigs.

Most raw materials he uses to build the houses are scraps abandoned by other people.

Recently, he shared photos of timeworn desks, old television sets and obsolescent stereos on social media with excitement, saying the things were donations from his friends and neighbors. "They are useless in others' eyes, but are treasures in mine."

Now, Qiao has several assistants who also have the passion to build such houses. The group is working together to enrich the tourist spot.

"I hope visitors can embrace a fresh experience every time they step into Land of Wilderness," he says.

Qiao's daughter was born last year. The couple say they hope their daughter will enjoy her childhood there.
