It's been a while since the finale of the TV series "Dajiang Dahe 3", and the ending of this drama can be said to be really uneasy, Lei Dongbao is emotionally scumbag, which is true, it is undeniable, but in the treatment of Thunder, as well as the people of Xiaolei's family, Lei Dongbao can definitely be said to have a clear conscience, but in the end, Lei Dongbao was paralyzed by a stroke in anger, and the people of Xiaolei's family are definitely to blame, and Lei Zhengming and Shi Hongwei are the culprits. 
In the end, there are many regrets in this drama, such as Song Yunhui and Liang Sishen did not get married, and their son was not born in the end, which is indeed very surprising. However, these can be answered in the fourth season, Zhang Xincheng and Song Zuer, Wang Yanlin and others starring in the TV series "Difficult Manufacturing" is actually "Dajiang Dahe 4", which tells the story of the manufacturing industry between 1998 and 2008. 
The first three parts of "Difficult Manufacturing" and "Big River" can be said to be closely related, and the reason is very simple, because the endings of Lei Dongbao, Yang Xun, Song Yunhui, Liang Sishen, Wei Chunhong and others are all in this drama, and they also appear in this drama, and since Thunder was taken away by Lei Zhengming and others, the endings of the three protagonists are very different, what will happen to them in the fourth part? 
Lei Dongbao was paralyzed by a stroke in the third season, his body couldn't move, and his mouth was crooked, but everyone can see from the poster that Lei Dongbao has gradually improved in the fourth season, his mouth is not crooked, and his condition is much better, and he is gradually able to move. In fact, in the fourth season, he lived in Yang Xun's hometown for a period of time, and after recuperation, he was gradually able to move, and naturally it was impossible to continue to be "isolated from the world". 
According to the description in the original book, although Lei Dongbao lost Thunder (Thunder was bankrupt at that time), Song Yunhui and Liang Sishen were already rich at this time, Liang Sishen owned her grandfather's billions of family property, so he opened a restaurant called Haoyuan with Yang Xun and Wei Chunhong, this Haoyuan is indeed very luxurious, Yang Xun is very rich, and Wei Chunhong invested in houses and shops and made a lot of money, so the four of them participated in the shares, and the Haoyuan was opened. 
Since then, this mansion has become the "canteen" of this group of people, after Lei Dongbao was able to move, he and Wei Chunhong were responsible for taking care of the mansion together, Wei Chunhong had experience in doing restaurants before, so it was natural for her to be responsible for taking care of it, not to mention that Lei Dongbao could also help, and he would not be idle and uncomfortable. In order to study abroad, Ren Yaoer took his children abroad, and Yang Xun simply "ate" in Haoyuan to entertain friends and customers. 
Song Yunhui and Liang Sishen's status in the fourth quarter is considered to be rising, plus their relationship with Yang Xun, they often eat in Haoyuan, so it is natural for people to think that they are a gang, Yang Xun is behind Song Yunhui and Liang Sishen, Yang Xun has done a part of the business, and it has a certain relationship with these two. Yang Xun had no backing, and after discovering such a situation, he did not object.
Yang Xun broke up with Liang Sishen and Song Yunhui and Yang Xun finally contracted out the entire shopping mall in the third season, he started anew, and as the people and industries he came into contact with were different, he gradually began to have some black-and-white feelings, plus Ren Yaoer left him, he was even more bent on going his own way. Yang Xun even cut off Liu Jun's finger because of a dispute, so Liang Sishen and Song Yunhui broke with Yang Xun directly after they found out.
Liang Sishen has actually been cheated by Yang Xun in the last season, the joint venture company, Liang Sishen appeared as a victim, at the beginning it gave people the feeling that she seemed to have been deceived by Yang Xun, Yang Xun cooperated with her, but did not remind her that she should hire a cashier, from the perspective of friends, Yang Xun is not righteous, it is indeed inappropriate not to remind, but eldest sister, this is a shopping mall, you are not a giant baby, what rights and obligations do people have to remind you?
What's more, Yang Xun liked her at the time, and she herself said that she liked Yang Xun, which made him misunderstand, so Yang Xun thought that their relationship was no longer ordinary, and he never intended to deceive her, this was her own wrong idea, no wonder others. And her father came straight to the financial room and calculated three sums of more than 20,000 yuan, Yang Xun said that it was used in the inconvenient aspects of accounting, Yang Xun said it clearly, but what he didn't expect was that this one still didn't give up, saying that Yang Xun **, and also threatened with the company law, so that Yang Xun had to kneel, and finally it was a set of combination punches to return Yang Xun's more than 10 million to the Liang family, Yang Xun lost everything, and the Liang family earned more than 10 million at once, which was simply a win.
And this time Yang Xun did something ruthless, but he didn't do anything between Liang Sishen and Song Yunhui, even if he took advantage of the situation, it didn't affect their reputation, but they directly wrote a blank check and let Yang Xun withdraw from the mansion, which was really surprising.
What Yang Xun did was indeed excessive, but was this incident really all Yang Xun's fault? Judging from the original work, to be honest, I really don't think that Yang Xun is heinous and makes Song Yunhui and Liang Sishen so disgusted with him. How can it be said that Yang Xun is their friend, but every time they have a problem with Yang Xun, they are targeted like this, and why did they choose to cover up when Liang Daolin broke the law and committed a crime? and what Liang Fan did, they didn't have the courage to stand up and expose it, the double standard was too obvious.
Lei Dongbao made a comeback with Yang Xun withdrawing from the mansion, Lei Dongbao and Song Yunhui became the bosses of the mansion, but Lei Dongbao knew that he and Song Yunhui and others were not all the way, Song Yunhui actually looked down on Lei Dongbao from the bottom of his bones, thinking that Lei Dongbao was shallow, he thought so when Lei Dongbao was in charge of Thunder before, but Liang Sishen's grandfather said that Song Yunhui's method did not work and could not save Thunder, judging from Liang Sishen's grandfather's evaluation, Song Yunhui may not be as Lei Dongbao.
Liang Sishen used money and power to force Yang Xun to leave the mansion, you must know that this mansion symbolizes the relationship between Lei Dongbao and Yang Xun and Song Yunhui, they opened this mansion to a large extent to let Lei Dongbao have a little career of his own after losing the thunder, or to make Lei Dongbao forget his hatred, but it turned out to be Liang Sishen and Song Yunhui's "fair trial ground", which is somewhat confusing.
Even if Yang Xun is wrong, even if he is heinous, he still respects Lei Dongbao, and treats Song Yunhui as his own brother. Or maybe it's to show how just they are and do the right thing for heaven. If it is the latter, then please deal with your own problems first and then do the right thing for heaven.
And Wei Chunhong has always believed in Liang Sishen's words, she has been speculating in shops and houses all these years, and began to speculate in houses in the nineties of the last century, Wei Chunhong has accumulated a lot of funds, and she is definitely not an ordinary person, and she also chose to quit the Haoyuan after Yang Xun left, Haoyuan symbolizes the friendship of the three, so far the friendship between the three broke down and completely parted ways.
Although Lei Dongbao lost everything, but he made a comeback, in fact, as long as Lei Dongbao firmly took Wei Chunhong's road, speculated in real estate and real estate, and made money lying down in the next ten years, he didn't have to worry about Waterloo at all.
Therefore, the third season of Lei Dongbao is indeed miserable, but his ending in the fourth season is still good, and it is not an exaggeration to say that he is making a comeback, but he changed the track, and whether he will still be entangled with the Xiaolei family in the future, I don't know, but he has experienced it once, he shouldn't be so stupid anymore.
Yang Xun was once again pitted by Liang Sishen compared to Lei Dongbao, Yang Xun and Liang Sishen, Song Yunhui and others experienced the matter of Haoyuan, he was pitted, and he was cheated again. Counting the fourth season, Yang Xun was cheated by Liang Sishen at least twice, the first time was Haoyuan, he was forced to quit by Liang Sishen, Yang Xun didn't ask for a penny, he left Haoyuan.
Later, Yang Xun's business became bigger and bigger, when he finally invested in real estate and industry, because the industry was too expensive, and he also fancied coal mines and other businesses, Liang Sishen calculated, Liang Sishen wanted to buy the city machine, so he used his power to make Yang Xun squeezed out of the city by his business partners, and then used Yang Xun's psychology of being anxious to invest, deliberately revealing his strength, ** Yang Xun sold the land of the city machine to himself at a low price, and finally Yang Xun sold the land.
Liang Sishen is so righteous and awe-inspiring, but guess who she gave this benefit to? She used her grandfather's assets to help others "lay eggs", bought a machine in the market, let Liang Fan and Liu Jun join in it, and made a lot of money, while Yang Xun's land was sold for one billion, and he lost hundreds of millions, a heavy loss.
She pit Yang Xun because Yang Xun borrowed her fame to do something, so she "presided over justice", so Liang Fan was perfect? Liang Fan has dared to have a lot of strength over the years, right? Use the power of the Liang family to fake the tiger, forget it, she almost sent her father in the last season, but she can forgive it, favoritism over the other, the top double standard is probably like this, in short, Liang Sishen's character in the fourth season is definitely unlikable.
In short, Yang Xun was cheated by Liang Sishen twice in the fourth season, and he finally talked to Liu Jun on the plane, in fact, it was still very pertinent, and there was no emotion in the evaluation of Song Yunhui and Liang Sishen, which shows that it is pertinent, whether it is in terms of bearing or vision, Yang Xun is actually more fair, as for Song Yunhui and Liang Sishen, if it were not for their backs to the Liang family, I am afraid that they would have been swallowed by whales long ago.
All in all, Liang Sishen and Song Yunhui's character was completely ** after the fourth season, and Lei Dongbao made a comeback, of course, changed the track. Yang Xun was cheated by Liang Sishen twice, but he was alive like Xiaoqiang and was able to make a comeback, even if the investment failed and he was in debt, he could still go abroad with tens of millions of funds to find a wife.
It can only be said that Liang Sishen is lucky enough, born in a place like the Liang family, her grandfather gave her billions of assets, and there is a big tree of the Liang family behind her to shelter from the wind and rain, otherwise with her character and ability, she is afraid that she will not survive more than two episodes in the business field.
