Lingqu is a great project created by working people in ancient China. It is one of the oldest canals in the world and has the reputation of "the pearl of ancient water conservancy buildings in the world".
After Qin annexed Korea, Zhao, Wei, Chu, Yan, Qi and other six countries, in order to open up Lingnan and unify China, Qin Shihuang ordered General Tu Youyou to lead 500,000 troops and divide them into five armies to go south to Guangdong in 22 1 year BC. Every army wants to occupy a major pass in Wuling, and one of them has occupied the mountain pass at the junction of Hunan and Guangxi provinces.
At first, Qin Jun was resisted by local barbarians, but failed to conquer it for three years, making it difficult to transfer the pay.
In 2 19 BC, Qin Shihuang ordered Yu Shilu to be in charge of military supplies and led soldiers and civilian workers to build artificial canals between Xiangjiang River and Lijiang River in Xing 'an to transport food.
In 2 14 BC, the Lingqu was dug, and Qin Jun quickly unified Lingnan.
In the 18th year of Jianwu in the Eastern Han Dynasty (42 years), the cross-toed woman rebelled against the imperial court, and Emperor Guangwu of Han Dynasty sent Fu Bo general Ma Yuan south to continue dredging the Lingqu.
In the year of Bao Liyuan in the Tang Dynasty (825), the Lingqu burst its banks and could not be navigable. Li Bo, the ambassador of Guangui, ordered the stone foundation to be built into a plowshare barrage, that is, large-scale and small-scale, so that the river could be diverted to the south and north canals, and steep gates with high water levels were set up on the south and north canals to facilitate navigation.
In the ninth year of Xian Tong in the Tang Dynasty (868), the Lingqu was steep and completely destroyed, and the river channel silted shallowly. At the site of the history of danger, a 40-mile embankment was built with stones along the river, and wooden stakes made of large solid wood were planted as steep doors.
In the fourth year of the Northern Song Dynasty (1044), Qin Sheng supervised the repair of the Lingqu in Yaqian, Guilin, which was completed in February of the following year.
In the third year of Jiayou in the Northern Song Dynasty (1058), it was mentioned that the Lingqu was built in Li Shizhong, the head of the Guangxi Criminal Prison, and it was completed in 34 days. This maintenance adopted the method of "burning stones to attack and guide away", cleared the reefs in the canal and increased the number of steep ridges in the Lingqu to 36.
In the 5th year of Shaoxi in the Southern Song Dynasty (1 194), Zhu Xiyan, the ambassador of Guangnan West Road and the ambassador of Zhijing Government, restored the Lingqu. /kloc-construction started in early February and will be completed at the end of the month.
From the 14th year of Yuan Dynasty to Zheng Zheng (1345), Lingqu was built by Su Zhenglian, the deputy envoy of Lingnan Guangxi Road. Construction started in September and was completed in January of the following year. The steep gate of the collapsed pier was repaired and made it navigable.
In the 29th year of Hongwu in Ming Dynasty (1396), Yan Zhenzhi, the producer, presided over the restoration of Lingqu, which started on September 1 1 and was completed at the end of September1. Due to the large-scale and small-scale heightening, the two water-crossing culverts discharge less water, and when the bank is destroyed by flood, the flood flows to the North Canal, and the South Canal is shallow, so it is impossible to navigate, which affects farmland irrigation.
In February of the second year of Yongle in Ming Dynasty (1404), the maintenance continued.
During Chenghua period of Ming Dynasty, the Lingqu levee was seriously damaged due to flooding. Governor Shan Wei of Quanzhou presided over the maintenance, and all 36 steep slopes were repaired.
In the fifty-third year of Emperor Kangxi of the Qing Dynasty (17 14), Governor Chen Yuanlong led provincial officials to donate money to repair the damaged fish scales. Instead of paving the dam top with huge stones, it was built into a turtle back, and feldspar was used to replace the fish scales that accumulated eggs.
In the 19th year of Qianlong reign (1754), the Governor General of Guangdong and Guangxi ordered the restoration of the Lingqu, while Gui, Ping, Wu and Yu watched, and appointed Fu Ming 'an as the chief restoration officer, Tongzhi Charley of Qingyuan Prefecture as the deputy restoration officer, and Ling Liang of Xing 'an County as the successor restoration officer. Renovation is carried out in two stages, from 19th year of Qianlong 1 1 month17th to128th February, and from 20th year of Qianlong's spring to 24th March.
In the 24th year of Jiaqing in Qing Dynasty (18 19), Zhao Shenqi, governor of Guangxi, donated money to repair the Lingqu, which was supervised by Zhou Zhiyu, the magistrate of Guilin. Construction started on September 15, and was completed on September 20//KLOC-0, mainly for the maintenance of steep doors.
In the 11th year of Guangxu reign in Qing Dynasty (1885), floods destroyed dams and steep banks in the north and south. Li Bingheng of Guangxi Nursing Home asked for instructions to repair the canal, which started in January of the 11th year of Guangxu and was completed in May of the 12th year. The Lingqu seen today is roughly what it looks like after this maintenance.
The excavation of Lingqu communicated Xiangjiang River and Lijiang River, and opened up the north-south water channel, which provided an important guarantee for the Qin Dynasty to unify Lingnan. A large number of grain and grass are transported to Lingnan by water, and the material supply is sufficient.
Lingqu connects the Yangtze River and the Pearl River, forming a water transport network all over East China and South China. Since the Qin dynasty, it has played a positive role in consolidating national unity, strengthening political, economic and cultural exchanges between the north and the south, and strengthening exchanges between people of all ethnic groups.
