When did Bazhou immigrate?

I just finished reading this book, named treading on thin ice, which tells the story of community worker Yang Decheng who unexpectedly returned to ancient times because of his conscientious work and became the illegitimate child of Ding Jia-Ding Hao. Ding Hao has no right or wealth, and works as a coachman for his half-brother. But Ding Hao also has a dream, that is, to become a rich young man in this evil society, to walk the dog for fun, and occasionally flirt with a good woman. Although the dream is a little far away, Ding Hao doesn't think so. With the social experience accumulated by community work, Ding Hao should deal with the world and the world in all directions, seize every opportunity around him wisely, get out of the cage and fight for everything he wants. ? Finally? I hope you like it.
