Riddles mainly refer to the innuendo of things or words for people to guess, and can also be extended to things with mysteries. The riddle originated from the ancient folk in China, and it has evolved for thousands of years. It is a cultural product created by the collective wisdom of the ancient working people in China. On June 7th, 2008, Riddle was approved by the State Council to be included in the second batch of national intangible cultural heritage list.

The answer is the answer to the question raised in this riddle. Generally speaking, the number of words in the answer is very small, some are a word, a word, a phrase, some are the name or action of a thing, and at most only one or two poems. If the number of words in the answer is taught, it will be difficult for the riddler to make a good riddle, and it will be difficult for the riddler to guess correctly. Interestingly, some riddles can become riddles after the answers and riddles are exchanged. For example: pump (idiom 1). Pump is a kind of machinery, including air pump, water pump and so on.

The word "pump" means "stone" on the top and "water" on the bottom. Zhihu guessed the answer: get to the bottom of it. "Get to the bottom of it" is an idiom. On the other hand, using "get to the bottom" as a crossword puzzle (type a word), its answer is "smoke". The answer refers to the thing itself hidden in the turning point of the riddle, which is the hidden internal part of the riddle, and can also be said to be the answer to the question raised by the riddle.

The answer should not only conform to the inner meaning of the riddle, but also conform to the scope defined by the riddle, so that people will feel "suddenly enlightened" when they see the answer. Generally speaking, the answer to a riddle should be specific. A good riddle should have only one answer, not two or more.
