The story is probably: In the fifty-first year of Qianlong (1787), Luo Hengtai, a Hunan water transport official, was taken to Beijing to transport grain, selling illegal salt along the way and harming the people. On the way back, I passed Linqing House in Shandong Province, where I robbed and abducted women while there was famine. The victim, the Samui family, had no choice but to sell his wife Liu Ruilian to Luo Hengtai's official number. When the ship arrived in Suqian, it was unable to move forward because of the southeast wind and docked at the East Gate Pier. Liu Ruilian missed his family and cried on the boat. He met his brother Liu Fengxian by chance. He just came back from doing business in the south for many years. His name is Liu Wuju. Liu recognized the twin sister, only to know that there was a famine in his hometown, and Liu Wuju was willing to pay to redeem the twin sister. Luo Hengtai relied on power and resolutely refused. Suqian Haohanwang Sanleng and others were very angry when they heard about it. They contacted thousands of poor brothers, defeated the official ship in Dongguan, and rescued Liu Ruilian and the betrayed civilians. Luo Hengtai fled alone. During Daoguang and Xianfeng years, this story was widely circulated among the people, some were compiled into stories and legends, and some were compiled into piano books for singing, which had a great influence and was widely known.
