After the Substitute Marriage, My Whole Family Panicked

Everyone in the capital knows that Gu Huaijin, the minister of household affairs, has been in love for more than ten years and has not continued his love affair with her, and only dotes on his legitimate daughter Gu Jinghong. Until the eve of the old lady's sixtieth birthday, he knelt in front of the hall and begged his mother to recognize the mother and daughter outside the door, the concubine Sun Fuyi, and the concubine who looked almost exactly like his legitimate daughter, Gu Chenbi. My sister-in-law Gu Jinghong didn't want to marry into the Lu family, so she found Gu Chenbi and got straight to the point: "You marry Lu Linzhao for me, the terms are whatever you want. I want to enter the East Palace and be the most noble person in the world." In a substitute marriage, two people with similar faces exchanged their fates. * The Lu family is the head of the noble family in the court. Lu Linzhao is the young master of the court. He is rigid, harsh and unkind. Gu Chenbi knew that she was marrying high, so she tolerated everything after entering the door, learned the rules, received cold looks, and made things difficult for her... But not only did these people not know how to restrain themselves, even Lu Linzhao showed no partiality towards her. If that's the case, then I won't serve you anymore. She stopped fighting, snatching, and pretending. But when she really gave up her career, why did the whole family panic?
