Crossword puzzles establish the relationship between language and images. Whether it is a straightforward expression, metaphor, personification, symbol and other techniques, riddles can describe the characteristics of things concisely in short language, which can arouse children's thinking, thus establishing the connection between language and the image of specific things, which is a good exercise for children's language ability and imagination.
Crossword puzzles require people to observe things from multiple angles. This is almost the greatest charm of riddles. In the process of guessing riddles, children will realize that the same thing can be observed and expressed from different angles, thus opening their thinking space. Therefore, it is not an exaggeration to say that riddles are a kind of "intellectual gymnastics", which also requires a serious attitude, and every detail can not be let go.
