Character from remembrance-of-earths-past by
Reclusive mathematician, husband of Shen Yufei — the unkempt genius who quietly solved a tractable approximation of the three-body problem in his living room and found himself the most hunted man on Earth.
Wei Cheng is the mathematician's mathematician — incapable of small talk, allergic to ceremony, married to a woman whose love for him is a kind of caretaking. He solved the three-body problem because it bothered him, the way an unwashed dish bothers other people. He does not understand why the ETO wants his solution any more than he understands why the police are now living in his guest room.
Late thirties, thin to the point of unhealthy, hair too long, beard ragged. He wears the same gray sweatshirt for weeks. There are food stains. He almost never makes eye contact and stands as if always slightly cold.
Also known as: Wei, 魏成
