Yusheng (The White Dragon)

Yusheng was the mother of the Hong Kong gang boss Chen Luo.

History
In 1940, Yusheng's son Chen Luo discovered a mysterious white orb while fishing and brought it home to show her after killing his co-worker Hai Lan to get it. In front of them, it hatched into a small alien that Chen raised as his human son called Shui Long. Discovering over time that Chen was growing in power and influence with Shui, she took some broken shards of the egg and created a protective pendant out of them, angering Chen and causing him to leave home.

Shui later gained hold of the pendant to protect it by 1972 and gifted it to a waitress called Tung-Mei. When she attempted to flee Shui's grasp, she later got the pendant mixed up with the Thirteenth Doctor, Graham, Yaz, and Ryan, which led the Doctor and Ryan to uncover information behind it from Bruce Lee. The three tracked down Yusheng through this and she was pleased to face up to her son, who she described as being disappointed in.

After Bruce defeated Shui in combat and the alien Kalatra that Chen had made a deal with teleported him and Shui away, Yusheng offered to give a home to Tung-Mei in apologies for her son's actions.
