Think about solving problems:

Fill in the familiar idioms with fixed collocation first, such as: It's a deal, it's a blockbuster, so the rest of the idioms can be calculated. In addition, we should also pay attention to the conversion between "two" and "two". Although both of them stand for "two" in numbers, they have fixed collocation in different idioms, such as killing two birds with one stone, killing two tigers with nine cows, killing two birds with one stone, killing two birds with one stone and so on.

Extended data:

There are more than 50,000 idioms, 96% of which are four-character, and there are also three-character, five-character, six-character, seven-character or above idioms, such as "pot calling the kettle black", "behind closed doors", "superfluous action", "haste makes waste" and "drunkenness is not about wine". Idioms generally use four words, probably because they are easy to grasp. For example, China's ancient poetry collection "The Book of Songs" has four sentences.

Some words of the ancients could have been aphorisms and idioms. Just because it was more troublesome to change it to four words, I had to give it up and use it as a guide. For example, Fan Zhongyan's "The Story of Yueyang Tower in Song Dynasty" has a good moral, which means "Worry about the world first, and then enjoy the world." However, due to the large number of words, idioms cannot be formed and can only be used as aphorisms.

The phrase "all wastes flourish" in Yueyang Tower is an idiom, because it is four words.
