訓讀係日本人睇漢文嘅時候，使用「乎古止點」（）喺文中寫低「 」同「 」之類嘅助字，用「返點」（）表示睇詞語嘅順序，用送假名、句讀點、片假名等作為閱讀嘅輔助，從而發展出嘅訓讀法。乎古止點、返點、送假名、振假名等各種訓讀漢文嘅標點，統稱「訓點」（）。
When Japan read Chinese, they use "hu gu stop point" ( ) to write down auxiliary characters such as " " and " " " " in the text, use "turn point" ( ) to indicate the order of words to see, and use kana, sentence reading point, katakana, etc. as reading aids, so as to develop training reading. Various punctuation points in Chinese such as ancient stops, return points, sending kana, and vibragana are collectively referred to as "training points" ( ).
