I recommend "The Beauty of the General's Door" to you. This novel is about the rise of war in the border area of the Great Sheng Dynasty. The five sons of the Zhen family generously went to the battlefield. The male protagonist transmigrated to the eldest son of an ancient family. The Matriarch of the family doted on this grandson, but the family was actually a chaotic place. In order to be able to live in retirement in peace, the male protagonist had to scheme against each other and try to deceive the Matriarch. I hope you like this fairy's recommendation. Muah ~😗
