　　By family influence, Sandra childhood began studying the "Book of Changes" Yi, and read, in particular the number of patients like the science of astronomy. He calculating, multi-talented. Guangwu late or Emperor Ming about the early (around 58 AD) as Sagong case of an. Yongping (AD 58-76 years) the early years, it was recommended by Wang Jingshan in flood control, of the Han Dynasty and Wang Jing-Wu was made with the success of dredging Junyi drainage. Yongping years (AD 69) Sandra also been instructed to repair the auspices of drainage and waterway transport lifeline Kaifeng Yellow River, and powerful. Yongping 15 years (AD 72 years) thanks to Sandra for the embankment Yezhe Emperor Ming. The early construction of seven years (AD 82) to move any of Xu prefectural governor. The following year they moved to Lujiang Prefecture and died in office.
　　Misunderstanding for flood control work, the existing record rather brief. Wang Junyi Wu with his dredging channels (which may be Kaifeng Kaifeng channel section), the king of Wu proposed by Ms Sandra "■ flow method, the water is no longer harmful." "■ Flow" may be set up by boiling water in the channel next to the weir, the water level within the channel can be controlled to protect the drainage dike safety. Yongping years beginning Bian drainage repair works can be traced back to the Western Han Dynasty when Emperor Ping (AD 1-5 years). At that time of the Yellow River, Kaifeng channels simultaneously burst, delay not repair. Han Jianwu years (AD 34), the only intend to repair dikes, to start soon, because of their resources behind the stop was made. Bian drainage after flooding the east, the old doors are in the river water, Yan, Yu-two states (now in Henan, Shandong area) people complaining. Yongping years, summoned Wang Jing of the Han Dynasty, asked water management strategy. Wang Jing Bian a comprehensive analysis of the river conditions, coping brilliantly, Emperor Ming greatly appreciated. Together with Sandra has successfully conducted Junyi Wang Wucheng drainage works, so give Sandra "Shan Hai Jing", "canals book", "Yu Gong map" and other river monographs, issued in the summer hundreds of thousands of soldier people to the king of Wu Jing-assistant, the implementation of governance Bian project. Sandra personally surveying the terrain, planning dike line. First construction of the Yellow River dike, from the Ying Yang (now Zhengzhou North) to Qian Cheng Haikou (now the territory of Shandong Lijin), more than a thousand years long, and then proceed to repair Bian drainage. Kaifeng Yellow River navigation channel of communication of the Yellow River, Huaihe River two, is an important waterway began in the Warring States period channel. It quoted from the Zhengzhou Yellow River in Northwest, after Kaifeng, Shangqiu, Yucheng, Dangshan, Xiao County, to Xuzhou into Surabaya, re-entry Huaihe River. Because the situation often changes in the Yellow slip, how to maintain the stability of water is a major problem. Kaifeng Yellow River drainage in southern plain areas, yellow is often destroyed when Henan pan. Yellow River flood, the water port to control bad, too much water into the nullah, Bian pipes burst embankment also dangerous. Wang Jing Bian channels were in the straightening, dredging shallow, dangerous section of such reinforcement work, then "ten miles up a water gate, so more attention relative whirl, leak-free collapse of complex patients." All works completed in the summer of next year. Although Sandra attention cost savings of 100 billion cost of money still. Emperor Ming himself along the channel after the completion of inspections, and to restore the system to assemble superior officers in accordance with the preparation of the Western Han Dynasty. Wang Wu and other followers officials are due to drainage pipes and a meritorious promotion, Sandra is Lianshengsanji to Shi Yu Shi.
　　The early construction of seven years, Wang Jing Xu prefectural governor to move the following year they moved to Luzhou Prefecture. Lujiang area at that time, people not using cattle farming techniques, though no shortage of land, but due to limited manpower, lack of food and often bitter. Territory was founded in the Spring and Autumn period, created by the Sun Shuao Shao (voice is) Pei (in this Shou County, Anhui), radius of over a hundred years, but many have remained vacant. Sandra tissue repair people, and to develop appropriate management systems, erection of display ban. Also to promote cattle farming, land reclamation. Sandra will also teach local people sericulture technology, is growing by the rich territory.
　　Jing-River's historical contributions, has long been highly praised, there is no risk of the Millennium Sandra river is said. View from the historical records, Sandra embankment of the Yellow River after 800 years of experience no major diversion dike is also one of the few, indeed an ideal location a river.
