I chose the palace archives because I'd love to dig around and see if there are any records from early, post-ancient war era Dixing where they talk about Shen Wei and Kunlun. (I'm assuming in this scenario that I have a temporary "reading languages I don't know" power or babel fish or something. ;-p)

Alternatively, if Wu Tian'en didn't mind, I'd love to visit his house and see what a private residence is like. (Not that they'd all be the same, but you know.)

In conclusion, I feel like a Dixing boyband would be amazing. :D :D :D

(Uh, full disclosure, I copied the second question from an old Guardian poll I did.)
