Crazy. How old is Gui Bao suitable for seeing?

Suitable for all ages. There are many cold jokes in comics, which are very humorous. It's all animated now. You can imagine how popular this work is. I am 20 years old now, and I still like this work very much. I know the author of this book. I often chat with the author on the Internet to see if I can relax and keep my mood in a happy state. I hope my answer can help you:)
