Junzhe Extended Universe

Junzhe extended universe is a term used by English-speaking fans of Gong Jun/Zhang Zhehan (Junzhe) to refer to crossover fanworks pairing up non-Word of Honor characters played by the actors Zhang Zhehan and Gong Jun.
These pairings are also sometimes known as JZEU, "junzhe universe", or in Chinese as 俊哲衍生 (Junzhe derivatives).
See Derivative Ship, Adjacent Ship, and actor-based crossover pairings for examples of this trope in other fandoms.
==History==
Early English-language primers indicated that only a predetermined list of non-overlapping ships were included in JZEU, but this practice seems to have ended, if it was ever true. As of late 2023, Zhang Zhehan's characters Zhang Min from Everyone Wants to Meet You and Xu Jin from The Blooms at Ruyi Pavillion are each paired with 12 Gong Jun characters (not including threesomes) in fanworks on the Archive of Our Own. The Chinese video-hosting service Youku shared official music videos featuring a crossover between Gong Jun and Zhang Zhehan's firefighter characters from The Flaming Heart and The Bravest, 13 April 2021., fail_fandomanon comment, 2021-09-21., but the other JZEU ships are pure fandom inventions. 
On AO3 fans started posting JZEU fanfics in Chinese starting in April 2021. English-speaking fans started posting in October 2021.
JZEU was nominated as a fandom for Yuletide in 2021, but rejected on the grounds that the exchange wasn't designed to handle this type of fandom., comment thread in yuletide-admin, September 20th, 2021. Instead, various JZEU canons were nominated, and fans wrote three LingYue fics (Begin Again and Brother). Later, JZEU pairings were allowed in several LLD AO3 fests and exchanges.
JZEU became popular in the DZZS discord server, and was included in several server gift exchanges. DZZS may be responsible for JZEU's continuing popularity in English fandom, as well as some of the more mysterious AO3 fanon tags like "Pearl Chicken Endorsement Universe".
As of November 2023, at least 654 JZEU fanworks have been posted to AO3, 302 in English. (bookmark collection updated on 22 November 2023.)
