The veteran Taiwanese singer-actress Tang Na (also known as Nana Tang), who recently passed away from lung cancer, was not a smoker. 
According to a statement from her husband, American-Jewish businessman Xue Zhiwei (Jeffrey Schwartz), Tang Na "did not drink or smoke and was very particular with what she ate". She also practiced kung fu and tai chi for 14 years. 
She was diagnosed with stage four lung adenocarcinoma in 2021, despite her healthy lifestyle.
