Outing in Autumn

I served as an official for my brother, and after seven years in the officialdom, I have become your minister. His father died suddenly and his brother returned. I became the eldest daughter of Gongsun Mansion again. It's a pity that the brother today is no longer the "look" he had back then. In just a few words, marry me off. On the wedding night, he lifted his hijab - "Is it you?" The conspiracy was uncovered and the truth gradually emerged. "Brother, may I have forgotten that Gongsun Shangqing, who was above the imperial court in the past, was my sister."
