What is Ten Wings?

The Ten Wings are ten commentarial appendices to the I-Ching, traditionally attributed to Confucius. They include the Tuan Zhuan (judgment commentary), Xiang Zhuan (image commentary), Xi Ci Zhuan (Great Treatise), Shuogua Zhuan (trigram discussion), Xugua Zhuan (sequence of hexagrams), and Zagua Zhuan (miscellaneous notes). These texts transformed the I-Ching from a consultation manual into a philosophical classic.
