Tianzhu, also known as "Eye of the Sky", is a kind of rare jewelry with strong ethnic and religious color, mysterious legend and special magnetic field. Tianzhu is mainly produced in the Himalayas such as Tibet, Bhutan and Sikkim. It is regarded as a stone by Tibetan compatriots. In addition, according to the records of traditional Tibetan medicine, the real pure dzi beads can not only increase human immunity, but also have a good effect on preventing stroke.

The dzi beads have one eye, two eyes and three eyes until nine eyes, twelve eyes and eighteen eyes. Generally speaking, the more eyes, the higher the price, but among many dzi beads, only nine-eyed dzi beads are regarded as "the king of dzi beads". Because' nine' is the largest positive number and has the noblest meaning, Tibetan compatriots all advocate this number. In the eyes of Tibetan compatriots, the nine-eyed dzi beads are a collection of merits and demerits, representing the strength of the world and the compassion of all beings. They are the most favorite and revered magical pearls of Tibetan compatriots and many Buddhist believers.

Because of the extraordinary blessing energy mentioned above, it is not easy to get a real Tibetan dzi bead. In Fu Zang, King Gelsall clearly recorded King Gelsall's oath when he opened the dzi beads in Fu Zang: "May the dzi beads gather in the hands of the deity and the guru, and may the dharma guard the dzi beads until a disciple of Fu Zang comes and delivers the dzi beads to this person." Therefore, Tibetans believe that having a dzi bead is the result of a lifetime of practice and blessing. If you get a dzi bead in this life, it is also a sign of success in practicing Buddhism in a sense.
