The tone symbols in the "Chinese Pinyin Plan" passed by the 60th plenary session of the State Council on November 1, 1957, and approved by the fifth session of the First National People's Congress on February 11, 1958 The methods used are: Yinping (ˉ), Yangping (ˊ), rising (ˇ) and falling (ˋ), and soft (no standard tone). This method solves the problem of distinguishing Chinese characters with different tones. For example, Ma mā (Yinping), Ma má (Yangping), Ma mǎ (up tones), scolding mà (off tones), and mɑ (softly without standard tone).

Solution:

Use the numbers 1, 2, 3, 4, and 5 to replace the tones Yinping (ˉ), Yangping (ˊ), and Up ( ˇ), gone tone (ˋ), soft voice (not marked) are the key marking symbols.

Implementation method:

(1) Use the number 1 to replace the Yinping (ˉ) symbol, because Yinping is the first tone. For example, the pinyin pīn yīn is pin1 yin1 according to this method.

Example words: acridine ah ah actinium The pinyin of pickled is "ā". Using this method, the pinyin of acridine, ah, actinium, pickled is "a".

The pinyin of Ai, Ai, Ai, Ai is "āi". Using this method, the pinyin of Ai Bie Ai Ai Ai Einsteinium is "ai1".

(2) Use the number 2 to replace the Yangping (ˊ) symbol, because Yangping is the second tone.

Example: suffer from cancer. The pinyin of suffer is "ái". Using this method, the pinyin of "cancer" is "ai2".

(3) Use the number 3 to replace the upper tone (ˇ) symbol, because the upper tone is the third tone.

Example: Ai dwarf Ai The pinyin of Ai is "ǎi". Using this method, the pinyin of Ai Ai Ai Ai is "ai3".

(4) Use the number 4 to replace the falling tone (ˋ) symbol, because the falling tone is the fourth tone.

Example words: Ai Ai Ai Ai Ai Ai Ai Ai Ai Ai Ai The pinyin of Ai is "ài". Using this method, the pinyin of Ai Ai Ai Ai Ai Ai Ai Ai Ai Yu Ai Ai is "ai4".

(5) Use the number 5 instead of soft sound, because soft sound is the fifth tone.

Example: The pinyin of the word ah is "ɑ". Using this method, the pinyin of the word "ah" is "a5". The pinyin of the word "ba" is "ba". Using this method, the pinyin of the word "ba" is "ba5".

(6) Note: According to the above implementation method, use numbers to mark the tone, and always mark the tone (number) after the syllable. For example: established cheng2 li4 extended information

The "Chinese Pinyin Plan" stipulates that "the tone symbols are marked on the main vowels of the syllables."

1. The main vowel is the main vowel, which is the vowel of the final. There are finals a, o, and e, and a, o, and e are the main vowels. With the single vowels i, u, and ü as finals, i, u, and ü are the main vowels.

2. To mark the tones, you must first read the pronunciation of the characters correctly, so that you will not mark the wrong tone. But when reading the correct pronunciation, please remember that there is a rule for marking tones: all tones are marked on the finals, but there are certain requirements on which finals they are marked on.
