Jia Sidao
Emperor Duzong's reign was plagued with rebellions, warfare and corruption in his court; many officials accused the chancellor Jia Sidao of corruption but Duzong trusted Jia Sidao who Duzong honoured by bowing down to Jia even calling him "teacher" and according to anecdotes, when Jia was considering resigning, Duzong knelt down in tears begging Jia to remain in office.
