At the 38th birthday party of Princess Daliang, the four-year-old granddaughter Cui Mianmian suddenly grabbed a cake and threw it at the princess. She was disrespectful in public and insulted the princess as she was old and ugly. She bluntly said that she liked Liu Ruyan more and wanted Liu Ruyan to replace her grandmother. The whole place fell silent for a moment, and no one dared to make a sound. The eldest princess looked cold and showed no anger, but her heart was already cold. Immediately afterwards, the eldest princess's daughter Mu Yueshu, her consort Shen Zhiliang, and her son-in-law Cui Mingyu stepped forward one after another and forced the eldest princess to agree to let Liu Ruyan enter the house in full view of the public. Faced with the faces of several people, the eldest princess beat her all the way. Not only did she deal with several people, but she also involved a bigger secret.
