From "Infernal Affairs 2", we learn that Chen Yongren and Ni Yongxiao are brothers.
However, because Chen Yongren is ni Kun's illegitimate son and has followed his mother's surname since childhood, Ah Ren's surname "Chen" is not "Ni".
This is explained in Chen Yongren's recollection of the police academy in "Infernal Affairs 2".

But Chen Yongren is the bloodline of Ni Kun after all, and since he wants to take over the Business of the Ni Family, he should restore his original surname to be more convincing to the public.
So why didn't Ni Yongxiao propose to change Chen Yongren back to his surname "Ni" after Chen Yongren returned home?
This is closely related to Ni Yongxiao's concerns and Chen Yongren's "selfishness".
<h1 class="pgc-h-arrow-right" data-track="5" >01.Ni Yongxiao's concern: Is this brother okay? </h1>
After Ni Kun, the head of the Ni family, was killed, the second brother Ni Yongxiao took over the Ni family's underworld business.
Not long ago, he was just an accountant and had never been directly involved in the family business.
His siblings, who share the same mother's name, are all legitimate professions such as doctors and lawyers, and they have no experience in managing gangs at all, and only a retiring third uncle can support the scene. On the surface, the Ni family is truly green and yellow.
Because of this, the four big men under the Ni family had no fear when Ni Kun just passed away.
But the four big men never expected that Ah Xiao's accountant status meant that he was a calculating person, and the name "filial piety" meant that his family concept was quite heavy.
Although including Ah Xiao himself, no one in the Ni family wants the family to do underworld business anymore.
But helplessly, the underworld is an "ancestral" industry and the root of the family, so Ni Yongxiao, who takes filial piety as the first, stepped forward at the critical moment of his father's unexpected death, picked up this mess, and hit the four big guys by surprise.
In fact, Ah Xiao's plan for the family business is very direct: after eliminating the forces that can threaten the family, support a trustworthy person to be the boss, so that the entire Ni family can "whitewash" and live a "high-class" life.
Who is the most trustworthy? Definitely someone who is related by blood. However, since it is naturally inappropriate for the whole family to "wash white", it is naturally inappropriate to find the family again, so Ni Yongxiao will set his sights on his father's illegitimate son Chen Yongren.
There is both blood relations and no explicit relationship with the Ni family, as long as Chen Yongren can sincerely "return" to the family, it can not only make the Ni family feel at ease to be a "high-class person", but also allow the roots of the family to be preserved.
But the question is, can Chen Yongren "return" to the family? This problem in front of Ni Yongxiao made him very annoyed:
First, he was not sure whether Chen Yongren's heart could be placed on the Ni family. After all, it is the father's illegitimate son, there has been no contact for many years, his growth process has nothing to do with the Ni family, and naturally there will be no so-called family bondage.
Can relying only on blood relations make Chen Yongren die to serve the family? Ni Yongxiao had no confidence.
Second, he did not know whether Chen Yongren's ability was enough to sit firmly in the position of boss. After Chen Yongren "went home", Ni Yongxiao found that although Chen Yongren was doing things sharply, he was too sharp and not very sophisticated, and he was not the material for the underworld.
Out of these two concerns, Ni Yongxiao did not let Chen Yongren change his surname to Ni at the first time, because in his eyes, this brother had not yet passed the "inspection period", and whether he could bear the burden of the Ni family's underworld business was still unknown.
From the later plot, we can know that although Ni Yongxiao did not necessarily confirm Chen Yongren's undercover identity, his concerns were actually very accurate, and he was worthy of being a calculating person.
It's just a pity that he is too affectionate, and in the end, he was fiercely swung by Han Chen, who was completely open-minded.
<h1 class="pgc-h-arrow-right" data-track="29" >02.Chen Yongren's "selfish heart": I am a "sir"</h1>
Many people after watching "Infernal Affairs 2" will have the idea that Chen Yongren is a righteous and exterminatory relative.
However, the reason why Chen Yongren chose between relatives and justice, is there really no "selfishness" at all?
In fact, it can be seen from his original intention of choosing to be a "Sir".
Ni Kun is a notorious underworld, and people show fear for him, but actually hate and despise him.
Although Chen Yongren is only his illegitimate son, in the eyes of others, he is not only the bloodline of Ni Kun, but also the "black second generation" who is not protected by black forces, and it is not difficult to imagine what kind of bullying and discrimination he will suffer in the process of growing up.
Not only because he was an illegitimate son who lacked fatherly love since he was a child, but also because his father's relationship was bullied, Chen Yongren's hatred for the Ni family actually began to be conceived since childhood.
In the official drama novel of "Infernal Affairs", there was a plot in which Chen Yongren's mother advised him not to hate Ni Kun before his death. In this plot, Chen Yongren's reaction is described as "reluctantly reassuring his mother".
Therefore, whether it is based on the plot inference in the movie or according to the novel supplement outside the movie, Chen Yongren's setting is not the selfless type of the Grand Duke, and the reason why he wants to be Sir Ya itself is that there is a "selfish heart" to avenge the Ni family.
For this reason, even if Ni Yongxiao proposed to let him change back to his original surname, Chen Yongren would not choose to agree.
First of all, he himself does not agree with the Ni family, naturally he will not sincerely "return" to the family, even if he can feel the care of his brother in Ni Yongxiao, he will only feel that the other party has other plans and wants to use him.
In addition, compared with Liu Jianming's confusion between black and white, Chen Yongren has always been very clear about his position because of his strong hatred for the underworld, and will never go beyond the thunder pool.
Even at the moment when Chen Daoming's identity was not clear and he was shooting at him for life and death, he only shot the other party's leg, and did not kill because he had the privilege of undercover. So don't say that changing your surname is only a superficial matter, for Chen Yongren, the surname Ni is a shame, he will only be the sir of the surname Chen.
I am a wooden branch of the dangerous building, what do you think about "Infernal Affairs 2": Why Chen Yongren "returned" to the family, Ni Yongxiao did not ask him to change back to his original surname"? Feel free to leave your comments below.
