Couplets were an art form in traditional Chinese culture, usually consisting of two neat short sentences. The top ten couplets definitely referred to the ten basic antithetical structures commonly seen in couplets. 1. Opposite tones: The tones are alternating between flat tones, such as "flat tones" and "flat tones". 2. Rhyming antithesis: At the end of each sentence, use the same or similar rhymes, such as "Ping Ze Ping Ze" and "Ze Ze Ping Ze". The pronunciation of different words in each sentence is relative, such as "The garden full of spring cannot be closed" and "The red window with snow is difficult to eliminate". The relationship between the two sentences is symmetrical, such as "Birds fly over thousands of mountains and disappear on thousands of paths" and "The sound of apes on both sides can't stop the light boat from passing through thousands of mountains". The meaning of the two sentences is relative, such as " white hair is 30,000 feet long and sad like a long hair " and " green mountains can't cover it, after all, it flows eastward." 6. Form antithesis: The form of the two sentences is relative, such as "The depth of the Peach Blossom Pond is not as deep as Wang Lun's love." 7. The content of the two sentences is relative, such as "a thousand miles together, the monkeys on both sides of the river can't cry". 8. The subject matter described in the two sentences is relative to each other, such as "The spring breeze is green, and when will the bright moon shine on me?" 9. Character Duel: The characters depicted in the two sentences are relative, such as "Picking chrysanthemums and leisurely seeing Nanshan under the eastern fence". 10. Antithesis of artistic conception: The artistic conception expressed by the two sentences is relative to each other, such as "a bosom friend in the sea is like a neighbor in the distant world". These 10 couplets definitely play an important role in the creation and appreciation of couplets and are also an important part of Chinese culture.
