Doubao (whose real name is Shen Ning) was a refugee due to war when he was a child. He was adopted by an old craftsman from a weaving workshop in Jiangnan, and he changed his name to "Doubao" (because he was hungry and cold as a child, and he most wanted to eat hot bean buns). She is smart and tenacious, has acquired top brocade weaving skills, and is able to weave the lost technique of "opening the warp and cutting the weft". She has a soft personality on the outside but is strong on the inside, and hides an unknown secret of her life experience.
