My favourite book is Journey to the West. It is one of the four Chinese literary classics. It was written by Wu Cheng’en.
The book tells us about stories of four main characters. After getting over many difficulties on the way to the West, finally they made it. Among the four characters, the Monkey King is my favourite. He is so smart and brave that he can protect others well. He never gives up when he faces difficulties and challenges.
The book has taught me not to give up or doubt myself. I have read the book several times, I’m not tired of it. If you have never read Wu Cheng’en, I recommend the book to you.
That’s all. Thank you.
