Wu Guang
It was said that the tactics Xue engaged to collect wealth for the emperor was this: he would secretly collect evidence of crimes committed by rich people in the populace; he would then arrest them and confiscate their wealth. This included pounding the arrestees on both their chests and backs, and using heated copper to burn them. In 933, there was a time when a powerful local man of Jian Prefecture (建州, in modern Nanping, Fujian), Wu Guang (吳光), went to Min's capital Changle (長樂, in modern Fuzhou, Fujian) to pay homage to the emperor. As Xue wanted to confiscate Wu Guang's wealth, he began to secretly look for evidence of crimes to use against Wu Guang. Wu Guang found out, and he led his followers, over 10,000, in defecting to Min's northwestern neighbor Wu.
