Era: Starting From Marrying The Wrong Sister-in-law

Rebirth in the midsummer of 1988.
Lu Yang was an orphan. When he was 13 years old, he was accepted as a carpenter's apprentice by the old man Yin from the same village. He was also regarded as a son-in-law to reserve talents. Seven years later, his 18-year-old childhood sweetheart fiancée was admitted to Qingbei University and resolutely regretted the marriage. Old man Yin, who was already the richest man in the village, could not stand his daughter. He approached the newly reborn Lu Yang and promised him a sky-high dowry. He was willing to exchange his stuttering daughter for his eldest daughter's marriage.
Both are childhood sweethearts.
Did Lu Yang choose to forcefully marry his sister, a top student, and become a son-in-law who stepped in on her doorstep? Or did Lu Yang choose to follow the trend, marry his twin stuttering sister-in-law, get this "sky-high price" dowry, and have the first pot of gold in his life.
After rebirth, he once again came to a crossroads in life.
On his southern tour to Qiming, he was looking at the vast ocean, and China was stirring up all kinds of businesses. As long as he stood in the wind and dared to think and act, even pigs could take off. He was opening his mind, waiting for him to use his hands to describe a blueprint of his own.
