After Jiang's parents died, she lived with her aunt, while her father was sentenced to prison. He was adopted by Xu Zhenran's father when he was a child. There are no relatives or reasons with the Xu family. Why did Xu Fu adopt him? Of course, this is not Xu Fu's kindness, but the exchange of interests between the two sides.
It turned out that the real mastermind who killed Jiang's parents in those days was Xu's father, who just went to prison for him. For the future of Tang Xu, Tang Fu took the blame for Xu Fu, in exchange for Xu Fu's recognition of Tang Xu as his adopted son, and let him live a better life.
Subsequent plot
On the surface, Xu's father did keep his promise, adopted and gave him all the power of the company. Because of this, Xu often has an unpleasant relationship with his father. He thought his father was better than him, and he even said angrily that Xu Fu would hand over the company to Tang Xu.
In fact, this is only a superficial phenomenon. How can a father not love his son and give the company to someone who doesn't want to do it? Xu's father did this because he used it. He trained Tang Xu to help him make money, and then transferred the money he earned to his own company. If one day the company's illegal behavior is discovered, Tang Xu will be pushed out to take the blame, just like his father, all the money will go to Xu Zhen, and everything will be on him.
