【答案】Dear Tom，
How are you!It's a pleasure to see your enthusiasm for learning Chinese and I'm sorry to hear that you are having trouble understanding Chinese idioms.Hopefully，my explanation will give you some insights into what may confuse you.
Chengyu are generally four-character Chinese sayings or idioms originating from ancient literature，history，and philosophers.These time-honored idioms reflects ancient Chinese wisdom，cultural customs and moral values we promote.The meaning of each chengyu usually surpasses the sum of the meanings carried by those four characters.Take "shouzhudaitu" for example，its literal meaning is to guard a tree stump，waiting for rabbjye.ais.It came from an ancient story where a farmer came across a dumb rabbit running into a tree stump and killing itself.Then，the farmer thought such luck would happen without putting in any effort so he never worked a single day ever since.From the story，we can figure out the idiom's figurative meaning is to wait idly for opportunities instead of taking initiative or to trust things to chance.
In a word，unless you know the story from which the idiom was derived and its common usage，a chengyu will sound like random nonsense to a foreigner，so I strongly recommend you to go and buy a good chengyu dictionary.Should you have any further question，please don't hesitate to ask.
Yours，
