In the TV series The Pretender, why is Ming Tai the young master and Acheng the housekeeper?

In the TV series "Pretender", the main characters in the play are four brothers and sisters of the Ming family, the eldest sister Mingjiang, the eldest brother Minglou, the young master Mingtai and the housekeeper Mingcheng. However, the only real brothers and sisters of the Ming family are Ming Jing Ming Lou, and Ming Cheng and Ming Tai are adopted. Cheng is the housekeeper of the Ming family, but he has never done what a housekeeper should do. I think the four brothers and sisters are not brothers and sisters, but they are better than brothers and sisters. However, for some reason and the need to cover up our identity, we deliberately give people the illusion of intimacy.

Because the origins of Mingtai and Acheng are different, it is also important to have different positions in the Ming family. Let me talk about it in detail.

First of all, I think Ming Tai and Acheng have different identities and origins. This is mainly related to the origins of two people. Mingtai's biological mother died to save her sister Spiegel and her eldest brother Mingmu, and it was the Wangs who caused the car accident. Therefore, although Mingtai's mother's death was an accident, it was inseparable from Ming's family. Therefore, after Mingtai's mother died, Ming's brothers and sisters adopted Mingtai and made Mingtai the master of the Ming family. After all, he is the son of the benefactor.

Mingcheng is the adopted son of the servant of the Ming family who returned to righteousness. This is the identity gap, so it is very normal that he can't be the aboveboard master of the Ming family.

Secondly, due to the need of pretender identity, there are great differences in identity between Ming and Acheng. One is a military spy and the other is a double agent. It is precisely because of their different identities that they can carry out intelligence work more smoothly. For example, when Y?ko Minamida was assassinated, Acheng used his status as a servant of the Ming family to defraud Y?ko Minamida's trust with false dissatisfaction, thus killing Y?ko Minamida. This means that it is appropriate for Acheng to be a housekeeper. As a master of the Ming family, Mingtai can be used to fabricate something untrue at the critical moment to help them out.

In the end, the Ming family didn't favor one over the other because of their different identities. Although there are only two young masters and one young mistress in the Ming family, everyone with discerning eyes can see that Ah Cheng is loyal because the Ming family doesn't take him as an outsider, and neither his position at the family banquet table nor his dress is worse than that of Ming and Ming. It can be seen that the Ming family treats him the same emotionally, which is why everyone sees the Ming family who loves each other.
