The famous Xiaoshang Bridge is said to have been built in the fourth year of the Kaihuang reign of the Sui Dynasty, which is 584 AD, and has a history of a thousand years. If you look closely, you will find several traces of wheel tracks on the deck of the stone arch bridge. The person in charge of the scenic spot told me that in the past, this was the official road leading to the capital, and horse-drawn carriages often passed through the bridge. After years of rolling, the hard bridge deck was worn out by deep grooves by the wheels.
