Kuwei is described as having black hair that falls on his forehead, a wide brow, the gold eyes of a Shu. He's sixteen and young-looking. There is an extended period of time where Wylan looks exactly like him and it is only possible to tell them apart by the way they speak, and the fact that Wylan is a little taller than Kuwei and has a slightly different facial structure.
Kuwei is hard to get to know, lying about how well he speaks Kerch and imitating Wylan. He plays dumb as a way of entertaining himself and annoying Jesper. As well as being tricky, Kuwei is clever, spending time trying to recreate jurda parem and drawing in his journals.
He is also stubborn, as shown when he repeatedly makes it clear that he wants to go to Ravka once the auction is over.
Kuwei's father, Bo Yul-Bayur, tried to make a drug that would mask Kuwei's inferni powers. Instead he created the dangerous drug jurda parem and, fearing it would be used as a weapon by his government, sent samples to Kerch, asking for asylum for him and Kuwei. Before they could be relocated to safety, Kuwei's father died and Kuwei was attacked by the Drüskelle. Kuwei was kept prisoner in the Ice Court, and was forced to try and recreate the drug until he was broken out by Kaz Brekker's gang.
In Crooked Kingdom, he admits that life in Shu Han was not easy for him and his father.
