is there any book where i can know thêm about fantaisie creatures like what do they like and etc ?

Try searching for sách about folklore and legends. Fairies, myths, mythology and stuff like that.
I have noticed that there are differences in các câu trả lời to those types of các câu hỏi depending on the answer source. As an example, elves hoặc Những nàng tiên cá may have different descriptions and qualities from Celtic lore to Viking hoặc Eastern lore.
Hope that helps.
