I will say that for all Zhao Yunlan doesn't really get Dixing, he's actually completely correct about Hei Pao Shi's PR problem! Later in the show, a lot of the trouble comes from the garbled whisper networks about him in Dixing-- 'I heard the Envoy is a traitor', 'it was the Envoy who got us stuck down here', 'oh this guy is actually the Envoy, burning the treaty', etc. If only he could have better and more accurate/responsive information channels!
