神策军
Later, however, Emperor Wenzong's chancellor Li Xun came to find out that Xiao Hong was not truly Empress Dowager Xiao's brother. Xiao Hong, fearful that Li Xun would report him, ingratiated Li Xun by inviting Li Xun's brother Li Zhongjing () as a staff member. At that time, whenever the eunuch-commanded Shence Army () officers went sent out to serve as military governors, the other Shence Army officers paid for their travel expenses but required that they pay back threefold after they took office. One of Xiao's predecessors as the military governor of Fufang was a Shence Army officer, but died before he could pay back. The creditors were not satisfied and wanted Xiao to pay for his predecessor, but Xiao refused. When the creditors tried to collect from the predecessor's son, Xiao taught the son to seek intervention from Li Xun. Li Xun subsequently ruled that the son could refuse to pay the debts. After Li Xun was killed in the Ganlu Incident—a failed attempt by Emperor Wenzong, Li Xun, and Zheng Zhu to massacre the eunuchs—in 835, the powerful eunuch Qiu Shiliang, who commanded one of the two Shence Armies, thus came to resent Xiao Hong deeply.
