Jumping would have been easy: Just step over the bridgerailing and let go.
跳下也许简单：只需跨过桥的栏杆并掉下。

My mother-in-law no thanks, that helps you, please come to the old bridgerailing front, take a look at what's under the bridge?
＂婆婆不用谢，这事好办。您老人家请过来，到桥栏杆前面来，看看桥下有什么？＂。

The bridge was really quite high and at first no one dared to attempt it. All of us got up on the bridgerailing and pretended to jump. But after many pretend gestures, we dared not do it.
