I am unable to determine a reliable source of information about the correspondence between the origin of the kanji character 矯 and Vietnamese. Therefore, I will omit this section.

The kanji 矯 is a phono-semantic compound (形声文字). The left side is a radical called 矢（や） meaning "arrow". The right side is 喬（きょう） representing the phonetic element. The original meaning of 矯 related to straightening an arrow, then developed into a broader sense of correcting or rectifying.
