In 2015, Kasing Lung created a fairy world in his three Nordic Fairy Tale picture books, where live The Monsters, which are both good and evil, including Zimomo, Tycoco, Spooky and Pato. Among them, the most famous one is Labubu, a small monster with high, pointed ears and serrated teeth. Despite a mischievous first impression, Labubu is very kind-hearted and always wants to help others while accidentally doing bad things. No matter what difficulties we encounter, we should grin like Labubu, and naturally we will become happy.
