The eldest son of Ju Yan and Madam Ju. He has an extraordinary memory—he cannot forget anything, whether good or bad. Everything he has experienced is stored like connected paintings with sounds and scents. As a child he was wrinkled and unremarkable, but grew into someone with sharp brows, bright eyes, and striking looks. He recognized Pei Nai as not being Tang Mingzhi by observing her mannerisms, especially how she wiped her mouth. He once had his hair styled into a girl's bun by Pei Nai when he was young.
