Where is the origin of naivety?
This should refer to the "innocence" in Tao Te Ching, which is true, natural, true, naive and simple. These words are related to childishness, but the source is not important. The important thing is to see what you want to express. You need a scene to understand the true meaning of this idiom. I hope my answer is helpful to you. Thank you for adopting ∨.
