What are the classic jokes for children under ten?

I recommend you to read my first joke book. The interesting thing about this joke book is that it tells jokes from the perspective of children, and it is not as abstruse as the jokes heard by adults, so that children will feel bored if they don't understand it. The author of this book consists of five parts, with the protagonist "Lele" to write all kinds of embarrassing things that happened to him, including campus life and happy family. Can attract children from different angles.
