Chang uses the term "the evil-eye-resisting triumvirate" to explain dZi beads: First, the round designs are themselves eyes-- "good eyes" to scare away and repel the "evil eyes," warning all misfortunes to keep away. Second, the square designs symbolize a shield resisting the power of evil eyes. Third, the sharply angled tiger stripes represent power to fight back with great strength.
張宏實用「眼睛抗衡三部曲」解讀天珠：圓形圖案代表眼睛，用「好眼」去嚇阻「惡眼」，像是警告一切不祥之物不要靠近；方形則象徵與惡眼抗衡的盾牌；最後用尖角的虎紋圖案象徵奮力反擊、一擊成功。
