The dictionary app is designed to help you improve your Chinese language skills. It provides you with a set of free books that contain a lot of Chinese vocabulary, as well as an English translation. You can use it offline, so you can access it anytime and anywhere. It's a good idea to have this dictionary on your mobile device, especially if you're a frequent traveler or if you want to learn Chinese. It will allow you to look up words easily and get the correct pronunciation. The app is also useful for vocabulary building, as you can add all the words you don't know yet and learn them later on.
