These days, when musicians and musical genres are gradually diminishing to nothing, there is no canon of recordings; simply depending on some concerned individuals 'explications is equivalent to simply leaving behind written historical records. If people of the future one day wanted to reconstruct it, there would be no standards for learning it.
在樂人、樂種日漸凋零的今天，沒有經典錄音，只靠一些有心人的闡述，等於只留下了文字史料，假若後代人有天想重新拾起，也沒有學習的準則。
