Wu grew up in a poor family and studied hard under difficult conditions. He was deeply moved and determined to develop education. Later, when he learned that Xiang had entered Shu, he was eager to learn and set up education. At that time, after the chaos in the late Tang Dynasty, schools in Shu were abandoned. Wu built the Gong Xue at his own expense, built a school building, ordered people to engrave the Nine Classics in Chengdu according to the Old Book of Yongdu, and invited the late emperor to publish this book, which revived the once difficult education.
