Hi there @ms.zhangzb! I have checked your code, and the example works well —congratulations on some great work.
The only thing I did notice is that you wrote some of your comments like this:
/myself method/
Which broke the code. They should be like this:
//myself method
But apart from that, it was fine.
If you want to look at our finished example and check your work in more detail, see the links available at the main thread for this assessment — "Silly story generator" assessment
