Jiangxi collector helps unlock ancient wisdom

There is almost no space to stand in Xiong Wenyi's storeroom in Jiangxi province. It is filled with every kind of lock you could imagine, made from wood, brass and iron.

Xiong has been obsessed with collecting locks for more than 30 years. "I have over 10,000 items in more than 100 different styles, with the oldest one dating back to the Han Dynasty (206 BC-220 AD)," he said.

The collector, in his 50s, showed one of his prized possessions: a pull lock, which has a small hook with which to pull the key. Xiong held up another device that requires an extra step to unlock. "You have to turn the key and press the button on the bottom to unlock it," he said.
