Who Du is is not recorded in historical materials. During our investigation and visit, no one in the local area knew anything about him. Only the inscription on the tomb table says, "Take the Ming Sutra as an example and give it to the general, and distribute it to Sichuan and take care of the counties. When I first arrived in Sichuan to stand by, everyone should be rewarded with the ability to be a monarch ... You can get to know Du by rewarding the doctor of Chaoyi for wearing Hualing Salt to transport the Cantonese Road, that is, taking the Road as a coastal defense. " The bridge is located in the village group of Banqiao Village Garden at Jinding Town West 14km. Built in the Shunzhi period of the Qing Dynasty, it is a single-hole stone arch bridge with a total length of 14. 1 m, a width of 3.5 m, an arch height of 5.5 m and a clear span of 5.3 m. There is only one stone guardrail on the bridge deck, and the bridge is made of bluestone. Twelve dragon-cutting swords were originally hung on the top of the bridge arch. It is said that it existed in the fifties and sixties, but now it is gone.
The shape of the bridge is quite similar to that of Puji Bridge, but there is no record of the bridge in local historical materials. The local villagers said: "There is a tall bridge-building monument at the bridge head, engraved with the year number of Shunzhi. This bridge is the ancient Sichuan-Guizhou Road. In ancient times, there were many pedestrians, and it was the only bridge leading from the pine forest to Zunyi. " Because the monument to the bridge was destroyed, a monument in the cellar of a villager Zhu showed that the person who built the bridge at that time was the ancestor of the family six generations ago, and there was no evidence to prove when the bridge was built. The shape of the bridge is very similar to that of Puji Bridge, but it should be built in the late Ming and early Qing Dynasties. Jinzhuang Village, located four kilometers north of Jindingshan Town, is surrounded by Pingba farmland with crystal clear streams. Locals call it Sanshan Bridge. The bridge spans Dabanshuixi, and the breeze on the bridge brings bursts of grain fragrance, which is cool and pleasant. The total length of the bridge is14.4m, the bridge is 5m high and the clear span is 8.2m, all made of stone. The bridge deck is 9. 1 m long, 4.55 m wide and the bridge railing is 0.3 m square.
On the east side of the bridge deck, there are two stone tablets, one of which contributes to the construction of the bridge. It is 1 .28m high, 0.78m wide, 0.22m thick and1m long. The other monument is a monument, with a height of 1.45m, a width of 0.29m, a thickness of 0.23m and a cap length of 1. 12m. The two inscriptions are illegible and flaky. Only then did the next monument "Forty-nine Years of Qianlong" be built (17 10). According to the age of the inscription, this bridge has a history of 294 years. Despite its age, the main building of the bridge has been well preserved so far. Every spring, the surrounding farmland is covered with golden cauliflower, while bees gather honey, butterflies fly up and down, streams gurgle and bridges flow, and people form a beautiful landscape painting, which is an ideal place for sightseeing.
