Two years ago, Song Bo was diagnosed with a serious illness that gave him constant headaches which left him tired and depressed. The condition was so dire that he was convinced he would never marry or have children. But one day while browsing the internet, Song came across a listing on e-commerce website Taobao for a child-sized love doll. He purchased the 4’10” doll and felt a deep connection with it the moment it arrived. The $2,200 doll he named Xiao Die or “little butterfly” is now treated like the daughter he never had (hopefully nothing more than that).
