In the TV series "The Legend of Zhen Huan", the biological mother of the fourth elder brother has always been a mystery. Although the identity of the fourth elder brother's biological mother is not clearly revealed in the play, through some details and clues, we can deduce who the fourth elder brother's biological mother is.
First, let's review some of the episodes in the play. In the play, the fourth elder brother is a smart and talented character. His biological mother did not appear in the play, but we can see some clues from the words and deeds of the fourth elder brother.
For example, there is a scene in the play where the fourth elder brother is studying and his mother suddenly appears and brings him a bowl of hot soup. Although this scene is short, it can be seen that the mother of the fourth elder brother is a person who cares about him very much. In addition, the fourth elder brother also mentioned in the play that his mother was a very gentle and kind woman, which can also be inferred that his biological mother may be a court concubine.
So, in "The Legend of Zhen Huan", which concubines are likely to become the biological mother of the fourth elder brother?First of all, we can exclude the two protagonists, Zhen Huan and Shen Meizhuang, because they both have their own sons and daughters. In addition, Concubine Qi and Fucha Guifei were also excluded due to age and other reasons.
Then, the remaining possibilities are pure concubines and concubines. Concubine Chun is a smart and scheming woman in the play, but she does not have a son and daughter of her own. And Jia Concubine is a ruthless woman who will do anything to achieve her goals, but she does not have a son or daughter of her own in the play. Therefore, it is more likely that Concubine Chun will become the biological mother of the fourth elder brother.
To sum up, the biological mother of the fourth elder brother in "The Legend of Zhen Huan" is likely to be a pure concubine. Although this answer is not explicitly revealed in the play, through some details and clues, we can deduce this conclusion.
