In "Big River 3", after Liang Sishen and Song Yunhui were together, Liang Sishen's father was against it. He said this:First of all, in terms of cultural differences, your education and your hobbies do not overlap with him at all, don't you deny this? Besides, the families on both sides, what about you, are high, so your mind is relatively more direct, Xiao Song is different, he is from the bottom, through his own efforts, step by step to today, he is very good and hard-working, this kind of people, I have seen some, and I admire them very much, but it may be because of the hardships experienced in the process of growing up, so that there is a kind of ruthlessness in their character, and this ruthlessness may make them do something that you can't imagine at all, let alone do it. However, after watching the finale, I found that the really "ruthless" person was not Song Yunhui, but Liang Sishen's father. 
Liang Sishen's father is right, a person who has climbed up from the bottom must have a "ruthless" energy, otherwise his life will not go far. Song Yunhui has "ruthlessness", but this "ruthlessness" is his dedication to his career. 
At the beginning, the Pengyang factory was facing closure, but Song Yunhui insisted on going his own way and insisted on dragging the whole factory to engage in research and development. To this end, he has set strict assessment criteria for revenue generation. In the face of the system, he is not partial at all, because he knows that once he favors anyone, no matter what the reason, the system will not be enforced. With his perseverance, Pengyang Factory finally got a new life. Imagine, if it were someone with the background of the Liang family, would they go to great lengths to support the Pengyang factory? Even if it was Xiaola, he wouldn't make such a stupid choice. The exploits of their fathers made them develop the idea of "defending the city". Their starting point is the shoulders of their parents, so they can't go down, they can only go up. For them, conservatism means more than aggressiveness, so they would rather be icing on the cake than do something that doesn't see the benefits at all. 
However, Song Yunhui, who was born at the bottom, has nothing, so he can give it a go, even if he loses, it's a big deal to start again. That's why they're betting on the future. This is actually what Liang's father is unwilling to say directly. Liang's father relied on the elite, and what they cared about most was face, which is why he was reluctant to return to China after being punished. But Song Yunhui was able to face the gains and losses calmly. This is an advantage, not a disadvantage. Liang's father thinks Song Yunhui is "ruthless", but what about himself? His approach to Yang Xun is really "ruthless". Father Liang looked down on Yang Xun at all. At the beginning, Liang Sishen was doing business with Yang Xun, and Liang's father didn't care, wasn't he worried? That's because it's not time for him to make a move. He knew that Liang Sishen put the money into it but did not find someone to supervise it, but why didn't he remind Liang Sishen, but instead went to check the accounts when the project was almost completed? 
Liang's father checked the accounts, just to find a problem. In other words, he had already seen that Yang Xun no longer had much use value at this time. He grasped the timing very well. first found out the problem of "making false accounts", and then persuaded Liang Sishen to quit. Then, he used the power in his hands to ask the bank to give Yang Xun a loan and get back Liang Sishen's money. Subsequently, he hinted to the bank that Yang Xun could not repay the loan and supported Liang Fan to take over. When Liang Fan took over, it was when the project was about to be completed and the mall was about to open, so you can see if Liang's father had the right time to let Liang Fan "pick peaches". Yang Xun also came up from the bottom, how difficult it was for him to come along the way, Song Yunhui saw it, so even if Yang Xun was wrong, he was still willing to give him a chance. But what about Liang's father? From the bottom of his heart, he thought that Yang Xun was not worthy of such a big business, so he deliberately took care of it. 
Originally, Liang's father could let Yang Xun go and let Yang Xun and Liang Sishen continue to cooperate. But he was too selfish, so he instructed Liang Fan to take over, wanting to turn all the East China Sea business into his own industry. If it weren't for Liang's father's intervention, Liang Sishen's investment in the mall would have made a lot of money. In this matter, it is not that Liang's father is shrewd, but that he is narrow-minded and selfish. As an elite class, Liang's father also has a serious concept of "preference for sons over daughters". He didn't use his daughter Liang Sishen, but pressed the "treasure" on Liang Fan. Liang Fan went to Hong Kong to invest, relying on his support. He was punished, also because of Liang Fan's matter. 
From the few conversations between Liang Sishen's father and Liang Sishen, we can see that Liang's father is not at ease with Liang Sishen, he feels that she is not mature enough, and she is too Western in the world, which is not in line with China's national conditions, and he also repeatedly told Song Yunhui that he hoped he could help her. In terms of cooperation with Yang Xun, Liang's father also disagreed with his daughter's vision. However, Liang Fan's style, everyone can see that he actually doesn't have much real talent and learning, and even many times his methods are not advanced. But why did Liang's father support him so much? In the final analysis, it's because he is a man of the Liang family. 
Throughout the play, Liang's father is the most hypocritical, boasting about how noble he is, and at the same time he is more ruthless than anyone else. Such a person is terrifying.
