Do Huo Mang and Lan Ye really exist?

No, Huo Mang and Lan Ye are the characters in Forced Prostitution, the most fictional characters in Wu's works, which have nothing to do with reality, so Huo Mang and Lan Ye don't really exist. Huo Mang is a surrender hero in the works of Emperor Xi, a white jade bead in the high pavilion and a fierce beast in the underground boxing ring.
