Introduction to ancient wooden locks: Almost every household in Dayuan Ancient Miao Village has wooden doors with ancient wooden locks on them. The wooden lock craft has been passed down in Dayuan for more than 1,500 years, and the production has become more complicated. It has developed from one-core wooden locks to two-core wooden locks and three-core wooden locks. Masters Yang Huanlun and Yang Huanzhong, the old carpenters of the village, once made three exquisite three-core wooden locks, which were collected by the county as cultural relics. In December 2009, the Hunan Political and Legal Channel went to Gumiao Village to conduct a special interview on Mu Suo. The X-Files was filmed and broadcast on the TV station, causing a great sensation.
