As the only man in "Knowing or Not" who fell in love with Minglan step by step, He Hongwen gave up Minglan for a cousin who had married someone, which was really a pity, and at the same time, he Hongwen was fortunate that He Hongwen could swing at the idea of marrying Minglan for other women before marriage, and after marriage, he was not sure how many concessions Minglan would make, and Minglan did not marry him.
However, after Minglan met Cao Jinxiu's mother and daughter in the He family, He Hongwen made it clear in front of Mrs. He that he had already thought about not marrying his cousin, and he also planned to go to Mrs. Sheng and Minglan to show his attitude, although Mrs. He told him that the marriage was over, why couldn't He Hongwen explain to Mrs. Sheng that he was fighting for Minglan, but chose to go directly to the door to withdraw from the marriage?
Since He Hongwen was an old lady Sheng who went to see with an injury that day, everyone could see the traces of He Hongwen's face being taught by the Cao family, and it turned out that Cao Jinxiu had lost her fertility by the safflower instilled by the first master's mother, and she could not have children in this life, and He Hongwen's acceptance was her last hope. He Hongwen in the original work decided to give up Minglan because of this, and even with the right wife in the back, he hoped that the other party could treat his cousin kindly like Gu Tingye, and later changed his opinion after being calculated.
But He Hongwen in the TV series is obviously much stronger, he can come out and scold Cao Huixiu when she humiliates Minglan, he can also be indifferent to Cao Jinxiu's delicate crying, and he can also say that the decision not to accept his cousin as a concubine is already a hundred times better than the incompetent He Hongwen in the original work. However, the Cao family is the in-laws of the He family, and if He Hongwen rejects Cao Jinxiu and marries Minglan, he does not know how many messes he will have to clean up for the Cao family in the future, and he will not be able to get rid of it.
Therefore, He Hongwen, at the suggestion of Old Lady He, used Cao Jinxiu as a concubine in exchange for the He family's severed ties with the Cao family and did not have contact with each other, and completely got rid of this evil relative who hated the poor and loved the rich and the high and the low. Only in this way, He Hongwen violated Minglan's promise that he could not give Cao Jinxiu a name, or even let Cao Jinxiu stay in the He family, and He Hongwen had no face to mention the marriage to Minglan again, and naturally it was not good to delay the family anymore.
This is also the reason why Mrs. Sheng would later persuade Minglan to endure Cao Jinxiu, not because Cao Jinxiu could not have children, but because she saw He Hongwen's determination not to let Minglan be wronged. Later, when Rulan and Wen Yan would be arrested for personally, Xiao Tao did not also mention that the He family might care, and Minglan also said that if the He family did not want her because of this, she also recognized, it can be seen that Minglan is still willing to accept He Hongwen, if there is no Gu Tingye halfway out, it is estimated that Minglan will still choose He Hongwen in the end.
