My name is Jiang Chu, and I have been hidden in history for five thousand years. Until one day, I became the Su family's son-in-law inexplicably... Are you a professor of medicine? Do you look down on me? Sorry, Bian Que is my apprentice. Are you an antique expert? Do you look down on me? Sorry, this bottle was given to me as a urinal. I am a son-in-law, a son-in-law who has lived for five thousand years.
