Apparently, the homosexual love between Curly Fu, Peanut, and other male characters on the show like Mycroft and Moriarty is worth bring thrown in prison for. If you look at MTSlash, a Chinese fan-fic site, Sherlock is by far one of the most popular subjects, with over 4,900 entries — almost double the second most popular show, Supernatural. Suits, for some inexplicable reason, also has a devoted slash following.
And the stories get pretty vivid. Like this one which imagines Sherlock hooking up with his brother Mycroft Holmes (via a shoddy Google Translate, which adds another unintentional layer of humor to this):
Sherlock is a virgin, no doubt. [Mycroft] Holmes can feel the tension in his body. [He moved] his hand gently in a circular motion on Sherlock's thighs, trying to ease each other's tight, and the other hand on the young Holmes who explore up and down slightly thin body , juvenile unique smooth lines. He finally withdraw from Sherlock mouth, "Sherly, are you sure? ......" his younger brother did not answer, [he] just moved down his body.
Or this author, who imagined a Watson making out with an injured Sherlock:
When this kiss became more and more uncontrollable, John raising his hand against Sherlock's chest ... the heat burned on the face of incredible speeds approaching his ... He still could easily be the man to mobilize desire. But he must stop because he does not want a kiss and Sherlock rip wounds.
And some are just Chinese translations of slash fic in English. Really, really steamy slash fic:
The wet heat was a shock, and John gasped and let his head fall back. In response, Sherlock leaned forward and sank his teeth into John's neck. It was painful, and probably too soon, but John didn't want it to stop, the pain sending deliciously mixed messages down his nerve endings. He wanted more. A mental image of Sherlock just piercing his skin with his canine teeth sent a surge up his thighs and through his hips. That was new; it certainly wasn't something he would've ever thought he'd get off on.
The people who read this often refer to themselves as "Fu Nv" originating from the term "Fujoshi", which literally means "rotten women." "The term has become popular in China in recent years. Young women fantasize about beautiful men being in love and proudly label themselves "Fu Nv". It has also extended from just men in manga and anime to real-life male performers in TV drama and movies," Sina explains.
The Fu Nv would probably be something like the One Directioners who gobble up "Zarry" (Zayn + Harry) or "Ziam" (Zayn+ Liam) fan fiction. As Amanda Hess wrote for Tomorrow, some of this is a push against the contrived and now all to formulaic romance stuff that we've been shoving at teenage girls since the dawn of boy bands and Chistian Grey, which are, when you boil it down, idyllic love stories written by middle age men and women about people half their age, aimed at teens and young adults. (Draw whatever kind of parallels to the Chinese government and censorship you want.)
