Is there a novel about the Prime Minister's daughter, whose surname is Meng, and in which the male protagonist is a prince?

Yes, there was such a novel called "Painting Tang Lovesick Ode". The female protagonist was Meng Qinghuan, and the male protagonist was the Third Prince, Li Shanran. The story took place in ancient times, and it belonged to the category of transmigration novels. I hope you like this fairy's recommendation. Muah ~😗
