A chinese youkai who serves as the 3rd Stage Boss of Embodiment of Scarlet Devil, the 6th mainline game in the Touhou Project Series. She also gets most of the worst possible treatment from the fans, being called things such as lazy, useless, and "China".
Canonically, she's neither lazy nor useless.
She also may or may not actually be a dragon.
Stage 3 of EOSD graces us with the best girl in all of Touhou, Hong Meiling! It's just a freaking shame that she's one of the fandom's biggest butt-monkey's!
