The prayer flags in Tibetan are called "Tajue". I don't know whether this "Jue" reads Jiao or Ju, how it is written in Tibetan and which dictionary records it.
This is Tibetan. Tajue usually reads Jue, similar to an artifact. I can't think of it at the moment. We usually say that God uses the word Gongjue, but in Tibetan, Tajue and Gongjue have different feelings. And they are all transliteration, which can't be consistent with the original pronunciation. Not a standard Tibetan pronunciation. I don't know what you want to know. In a word, no academic literature is needed. Tajue is not only the name of the prayer flag pole, but also the prayer flag itself, which can be heard in the shouts of selling prayer flags in Lhasa. Prayer flags and prayer papers represent luck.
