As Jiedushi
It was said that during the years he was military governor, Wu Shaoyang did not pay homage to the emperor. As his territory had many plains and meadows, he cultivated husbandry of horses and mules. He often pillaged the hills of neighboring Shou Prefecture (壽州/寿州, in modern Lu'an, Anhui), which were known for growing tea, to rob the tea merchants. He also often accepted those persons who were under prosecution by other circuits and put them into his army. However, as he often submitted tributes of horses to Emperor Xianzong, Emperor Xianzong did not act against him.
Wu Shaoyang died in 814. His son Wu Yuanji initially did not announce his death and tried to obtain imperial sanction to succeed him. When Emperor Xianzong refused to grant him a commission, Wu Yuanji reacted by pillaging the surrounding circuits, and Emperor Xianzong declared a general campaign against him, eventually defeating and killing him.
