Biography
Zhao Yun Ru is a refined, sophisticated, wealthy, and successful businesswoman on the exterior. Her company, Tai Yong Medical, controls basically all of Heng Sha, and she has substantial investments in Belltower Associates. She is a major player on the global stage, and has big ambitions for herself and her company.

But on the inside, Zhao is a cutthroat, ruthless, and brutal woman that uses military force and corporate sabotage to drive her competitors out of business. She attempts to buy out all of her enemies, and when that doesn't work, she hires freelance hackers to steal their secrets. Despite her criminal activities, her substantial wealth and usage of Belltower as a private army renders her untouchable, legally or otherwise.

Deus Ex: Human Revolution
Jensen arrives at Heng Sha looking for a hacker, but finds out from Arie van Bruggen that his real enemy is none other than Zhao Yun Ru. With van Bruggen's help, Jensen manages to infiltrate the towering Tai Yong Medical facility, and finally confronts Zhao in her penthouse.

There she pleads with him, insisting that, like van Bruggen, she is only a hireling, and that others are more involved with the conspiracy than she is, including even Eliza Cassan of Picus fame. But this is only an act - once Jensen lets his guard down, she gets the better of him, activating her panic room and summoning a horde of Belltower bodyguards.

She reappears much later in the Omega Farm research facility as part of a trap set for Adam by Jaron Namir, attempting to shut off his augmentations using a remote control tied to a new biochip and then fleeing during the fight between Namir and Adam.

She appears again on the lowest level of Pancaea, desperate to reverse the effects of Hugh Darrow's killswitch and implement the new Tai Young Medical Biochip to control the augmented populace, she interfaces with the Hyron quantum computer before being killed by Jensen
