The prototype of Xiao Lei's family is Daqiuzhuang in Tianjin, and Lei Dongbao is the prototype of Yu. In the TV series, Lei Dongbao came back from the army as the secretary of Xiao Lei's family. He didn't want to see Xiao Lei's family continue to be so poor, and men couldn't marry daughters-in-law, so he took everyone to get rich. He studied the most advanced technology outside, from brick kiln factory to electric wire factory and breeding factory, and made Xiao Lei's family the richest village in the county through various kinds of investment attraction.

Xiao Lei's explanation.

In Dahe Opera, Xiao Lei's home is a poor mountain village. After so many years, no one wants to go to Xiao Lei's house. Many older men in the village can't get married. Just because they are too poor, no one wants to be a member of the Xiao Lei family. All this has changed since Lei Dongbao came back. Lei Dongbao is a demobilized soldier and has left his hometown for five years. I didn't expect to return to his hometown five years later, and there was no change at all. From then on, he made up his mind to lead the Lei family on the road to wealth.
