Interesting, I never thought to contrast him with Pingjing! I suppose that does work, though I find Pingzhang and Feizhan more appealing contrasts. Pingjing and Yuanqi should talk in the future as well.

(Random thought: I always thought Tingsheng using a different generation level character (ping vs yuan) was due to him being adopted and wanting to signify a sort-of break from the Imperial family, but I realized it's probably jsut because he adopted a kid who was already called Pingzhang.)
