This was a cute little story, packaged in an attractive book, with lots of helpful notes and vocabulary. It also used repetition of set sentence structures in different contexts, which was useful to be able to see how they are used in various applicable situations.
Although it is aimed at beginner to intermediate readers, it felt more like a children's book than one for adult Mandarin learners. Part of me doesn't mind that, because I am in fact an overgrown child, but part of me would have liked something that felt a teeny bit less juvenile, perhaps.
