Zheng Bao Yu

[1] Due to Marvel losing the rights to the Fu Manchu character, her name Fah Lo Suee was changed to Zheng Bao Yu.

Fah Lo Suee, is a devious mastermind in her own right, frequently plotting to usurp her father's position in the Si-Fan and aiding his enemies both within and outside the organization.

Editor-in-chief Roy Thomas agreed, but only if they would include the Sax Rohmer's pulp villain Dr. Fu Manchu, as Marvel had previously acquired the comic book rights to the character.

[13][14][15][12] In 2010's Secret Avengers #6–10, writer Ed Brubaker officially sidestepped the entire issue via a storyline where the Shadow Council resurrects a zombified version of Dr. Fu Manchu, only to discover that "Dr. Fu Manchu" was only an alias and that Shang-Chi's father real name was Zheng Zu, an ancient Chinese sorcerer who discovered the secret to immortality[16] and while the Si-Fan is referred to as the Hai-Dai.

[17][18] Similarly, Shang-Chi's half sister Fah Lo Suee was later renamed Zheng Bao Yu in 2013's The Fearless Defenders #8, written by Cullen Bunn, where he appears leading the Ha-Dai.

After obtaining her own faction of Fu Manchu's Si-Fan assassins, Fah Lo Suee would attempt to sway Shang-Chi into helping her usurp their father from his criminal empire, only to be rebuffed by her heroic half-brother.

Now in full control of Zheng Zu's Hai Dai assassins (formerly called Si-Fan), she resumes her father's long-forgotten experiment of bio-engineering Brood eggs as weapons.

With the help of No-Name of the Brood, the Fearless Defenders defeat the Hai-Dai and destroy the experiments, forcing Bao Yu to teleport away from her lair; she later confronts Caroline for not providing her with enough protection.

[30] The Marvel Cinematic Universe features Xu Xialing (portrayed by Meng'er Zhang), a character based on Zheng Bao Yui, Sister Dagger and Sasha Hammer.
