The “葵花宝典” (Sunflower Manual) is a popular Chinese meme that originates from wuxia (martial arts) novels, specifically from Jin Yong’s classic book The Smiling, Proud Wanderer (笑傲江湖). In the story, the “Sunflower Manual” is a legendary martial arts manual that promises unparalleled power to anyone who masters its techniques. However, it comes with a bizarre and infamous prerequisite: the practitioner must first castrate themselves. This bizarre condition makes the manual a source of humor and satire in popular culture.
