Tones in ancient Chinese can be divided into four categories: flat, rising, falling and entering tone, and these four tones can be divided into flat and falling.
In modern Chinese, flat sounds include yin ping and yang ping, while voiced sounds include rising and falling tones. According to the standard of modern Chinese, one tone is flat, two tones are rising, three tones are rising and four tones are falling. The ancient Rusheng characters have disappeared now.
The couplet is flat and even: "You should distinguish flat and even; No matter135,246 is clear "-for example, in a seven-character couplet, the first, third and fifth words can be flat or even, and the second, fourth and sixth words must be flat and clear (flat and flat, flat and flat).
Second, the bottom hole to be neat, must abide by the following rules:
1, words are equal and sentences are consistent. In addition to deliberately leaving the position of a word to achieve a certain effect, the number of words in the upper and lower parts must be the same, neither more nor less; Phrase structure is the same as sentence reading. (exception: Yuan Shikai has been through the ages; Long live the people of China! -couplets pay attention to neatness. This couplet is not neat. The first couplet is "Yuan Shikai", and the second couplet is "Sorry for the people of China", which means that Yuan Shikai is sorry for the people of China! It is deliberately used untidily to achieve ironic effect)
2. Be straightforward and have a harmonious tone. It doesn't have to rhyme, but it should be flat, that is, flat to voiced and voiced to flat, rhythmic and catchy to read. The upper end of the couplet is voiced and the lower end is voiced.
3. Parts of speech should be relative and in the same position. It is generally called "virtual to virtual, real to real", which means that nouns to nouns, verbs to verbs, adjectives to adjectives, quantifiers to quantifiers, adverbs to adverbs and related words must be in the same position.
4. Be content-related, from top to bottom. Link up and down must mean to connect with each other, up and down; In addition to the "overlapping words" in the upper couplet, there are "overlapping words" in the lower couplet (such as using compound words, overlapping rhymes, thimbles, etc.). ), in general, there can be no irregular repeated words and words in couplets.
