Cun Yu was born more than 500 years ago during the Reign of Hongzhi in the Ming Dynasty, and experienced the five dynasties of Hongzhi, Zhengde, Jiajing, Longqing and Wanli.He was called "Qiaotou Master" by the People of Heshun, because he lived in Heshun Daqiao (now the entrance of the Daqiao alley next to Heshun Library).During the Reign of Emperor Zhengde of the Ming Dynasty, Cun Yu was elected to the imperial court as an official of Honglu Temple, which was equivalent to the Protocol Department of the Foreign Ministry today.He was also a professor at Siyiguan, which is equivalent to the current professor at China Foreign Affairs University.Cun Yu not only understood Confucianism, but also mastered the Myanmar language, which contributed to the communication between China and Southeast Asia and South Asia.

According to historical records, in the Ming Dynasty, there were many heshun people in the imperial court for generations. There were as many as 11 heshun officials in the same dynasty, and Cun Yu's father, Cun Wenbin, had also served as the order class of Honglu Temple.

Cun Yu was very serious and dedicated when he served as the order of honglu Temple, so his good performance was praised by the emperor.In the eleventh year of Zhengde (1516), the emperor issued a special decree to commend his achievements, saying that he "worked diligently".In recognition of Cun Yu's erudition, mastery of foreign languages and diligent administration, the emperor conferred on him the title of Dengshi Zuolang.Cun Yu did not return to his hometown until he was in his 70s.Ming Wanli years, Tengyue participation Deng Zilong had book "white hair still work in the court" plaque, memorial Cun Yu's merits.It means that although Cun Yu has arrived at the white-haired seventy years of the emperor's reign, but also for the country.

Cun Yu is remembered for leading the people of Heshun to build rivers and control floods after he returned to his hometown.In the early Ming Dynasty, during the rainy season, the water level of the Daying River, which runs through Heshun Dam, rose and flooded.At this time, Heshun dam will become a vast ocean, the river will destroy the fertile fields.The people of Heshun are harmed by floods every year.After Cun Yu returned home, he used his prestige to mobilize the masses to repair the Daying river to control the flood.Folk said that "the master of the bridge built the river, and imitate the Yellow River of the nine bends and 18 bay."Under Cun Yu's leadership, flooding in Heshun was brought under control, and 6000 mu of farmland in Heshun became good farmland for drought and flood harvests.In addition, Cun Yu also funded bridges and roads, and did a lot of public welfare.Legend has it that the old bridge in the Double Rainbow Bridge at the entrance of Heshun village is built by Cun Yu.He also left a story behind.After the bridge was built, a monument was erected beside it, and the money left over from the bridge was buried at the bottom of the monument for later generations to repair the bridge.Unexpectedly, a group of passers-by pulled down the stone tablet in the dead of night and dug up the money buried under the stone tablet.

The republic of China veteran Li Gemyuan has praised the merits of inch jade poem: "the river winding around is the bridge master with people to build. A man with an eye, save the poor again."
