Ways to distinguish between upper and lower couplets

What is the sound of leveling? In the ancient and modern rhyming books, the characters are divided into four tones, the flat tones are called "flat" regardless of yin and yang, and the three tones of "oblique" are the upper, the upper, the upper, and the lower tones. Modern Chinese characters are categorized by yinping and yangping as "Ping", and by Shangsheng and Deheng as "Oblique". The classification of old and modern sounds should not be mixed in the same text. For example:

There have always been many elegant scholars in the world of simplicity, and poverty has bred virtuous men from time immemorial

鈪鈪鈪鈪, -鈪鈪鈪-

In the above example, "-" is a flat tone and "丨" is an oblique tone. "In the above examples, "-" is the level tone, and "丨" is the oblique tone. The word "elegant" is used to refer to the "breeding of the virtuous and the good". Regardless of the changes, the last word of the first line of each couplet must be in an oblique tone; the last word of the second line must be in a flat tone. Any work that does not meet the basic requirements of the rules of the couplet will not be called a couplet.
