Yang Dong Character Analysis in The Three-Body Problem

Yang Dong is Ye Wenjie and Yang Weining’s daughter. Born and raised near Red Coast Base, Yang grows up to be a brilliant, beautiful, and closed-off physicist. Having loved abstract theory from a young age, Yang struggles to cope—and ultimately commits suicide—when experimental data ceases to align with her theoretical expectations. As her mother Ye puts it, Yang Dong’s “world was too simple” and abstract, so she could not ever handle the messiness of real life.

Her father left behind some records. She listened to all of them and finally picked something by Bach as her favorite, listening to it over and over. That was the kind of music that shouldn't have mesmerized a kid. At first, I thought she picked it on a whim, but when I asked her how she felt about the music, she said she could see in the music a giant building, a large, complex house. Bit by bit, the giant added to the structure, and when the music was over, the house was done […] I failed. Her world was too simple, and all she had were ethereal theories. When they collapsed, she had nothing to lean on to keep on living.
