Parents, Feng and Li Na Chao


Lily has always wanted to make her parents proud of her. Intelligent, logical and a high achiever – she believes anything is possible if you work hard for it, Lily’s only struggle is with her bedside manner. She is blunt and speaks her mind and doesn’t care if she is liked or not.

Lily lives by her five year plan. She originally had her sights set on dermatology however seeing how rewarding life in the ED department can be decided to stay on after her rotation and be a registrar.

Lily was rocked by her father’s death in Series 30, she still felt like a failure in her father’s eyes and behind her tough exterior – she is just looking for that approval.

As the series have moved on, Lily’s character has developed. She is not always the stern hard face and can show a soft, sensitive side. The will-they-won’t they romance with paramedic Iain was just what she needed, however in the end she chose to follow her career path and head to Hong Kong, leaving a dejected Iain behind.
