This book is a really, fun, funny, hilarious and amazing book for kids and teens to read, it teaches you the Chinese four letter words knows as (成語) and makes you know the meaning of that particular four letter word! It might seem boring from the outside, but when you read the book it shows funny short script comic scenes that look like the ones in the mangas, and it's very funny. Overall it's a great book to read and learn, highly recommend!
