Jian Lan & Cuocuo Canon Review

The information about Jian Lan and Cuocuo is very scattered over the TGCF books, and often they are not mentioned by name, so I thought it would be helpful and perhaps entertaining to collect it all.
Note 1: I can't read much Chinese so don't take my occasional references to the original text as a sign that I've read it.
Note 2: Spoilers to the very end of TGCF.
The big thing that's missing from this as a canon resource is character profiles with introductions and descriptions of their personalities and relationships. For those, you will have to consult the Seven Seas appendices or the fandom wiki.
It would also be nice to add a gallery showing their designs across the different adaptations.
All feedback welcome!
