There are many fixed words in China. These words have three characters, four characters, five characters, even more characters, but most of them have four characters. Their composition is fixed and cannot be changed. Although the number of characters is small, they are often rich in meaning. These words are called idioms, such as “Racing ahead”, “Constant dripping wears away the stone”. There are many idioms in China， and their origins are different. Some derives from the fables in the book, and some derives from historical legends. These stories with certain characters and plots originally have a relatively large number of words, so people use very few words to summarize their meaning. In this way, they can be used in other places. Idioms are a special language phenomenon in China, and they are also related to the monosyllables of Chinese characters, because only monosyllable Chinese characters are more convenient to form fixed idioms. Idioms are the product of Chinese culture and also contain Chinese culture and history. Today, let’s learn a well-known idiom formed in Chinese history, Two Dogs Strive for a Bone, and a Third Runs away with It.
