Once upon a time, a fisherman in a Chinese village found a mysterious box in his net. It could be filled with precious jewels which would make him rich (good). But it also might contain something dangerous or bring him bad luck according to the superstitious beliefs in the village. This is a typical'maybe good maybe bad' Chinese story.
You can start with an uncertain event. For example, 'One day, I received a mysterious letter. I had no idea who it was from or what it contained. It could be good news or bad news.'
A boy bought a lottery ticket. It was a'maybe good maybe bad story'. He was excited about the possibility of winning a large amount of money. When the results came out, he didn't win the big prize. He was really disappointed at first. But then he realized that he had spent very little money on the ticket. And this experience made him understand that he should not rely too much on such uncertain things. Instead, he should work hard to earn money. So it was a bad thing in terms of not winning, but a good thing in terms of the lesson he learned.
