Baqiao is located in the east of Xi City12km, which is an influential ancient bridge. Baqiao, built in Han Dynasty, is a wooden beam and stone pillar pier bridge. It uses four circular stone pillars to form a stone pillar (with a stone pillar in the middle) and six stone pillars to form a light pier. Wooden beams are added to the pier and lime-soil slab bridge panels are laid. Is the pioneer of Shizhudun. In the Spring and Autumn Period, Qin Mugong took the lead in Xirong, changed Zishui to Bashui, and built a bridge, so it was called Baqiao.

In the third year of Emperor Huang (22 years), Baqiao Bridge was flooded. Wang Mang didn't think it was a good omen, so he changed the name of the bridge to Changcun Bridge. Later, it was destroyed several times in the Song, Ming and Qing Dynasties. In the forty-six years of Qing Qianlong (178 1), Shaanxi Governor Bi Yuan rebuilt this bridge, but the scale of the bridge is not what it used to be. It was not until the 14th year of Daoguang reign (1834) that Governor Yang Cai built it according to the old system. This bridge is 380 meters long and 7 meters wide, and there is a stone fence beside it. There are 72 holes under the bridge, each with a span of 4 to 7 meters, and 408 bridge columns. 1949, in order to strengthen Baqiao, the bridge was expanded and the original slate bridge was changed into a reinforced concrete bridge. Now the width of the bridge is 10 meter, and sidewalks with a width of 1.5 meter are left on both sides, which greatly improves road transportation. In the Tang Dynasty, a post station was set up on Baqiao Bridge. Most of those who bid farewell to relatives and friends and went to the East broke up here, and some even took folding willows as gifts. Therefore, this bridge was once called "ecstasy bridge", and the words "farewell every year, flying snow on Baqiao" were circulated. "Baqiao Snow Disaster" has since become a great scenic spot in Xi 'an.

1. That is, Xiwei Bridge. Emperor Wu of the Han Dynasty was built in the third year of Jianyuan (BC 138). Because it is opposite to Linmen in Chang 'an, it is also called Linqiao or Linmen Bridge. So the address is in the south of Xianyang, Shaanxi Province today. Xian yangqiao in the Tang Dynasty was the main road from Chang 'an to the Western Regions and Bashu during the Han and Tang Dynasties. Shortly after Emperor Taizong ascended the throne, he joined forces with the Turkic jaw Khan on this bridge. In the Tang Dynasty, Xiling Bridge was also a place to see off guests. For example, Wang Wei's "Weicheng Qu" said: "Weicheng is warm, rainy and dusty, and the guest house is green and willow-colored. I advise you to have one more drink. There is no reason to go to Yangguan in the west. "
