Rumors began to swirl on Monday that Chow had died, but her representatives denied the claims. However, late on Tuesday (Dec. 12) evening, Chow's studio confirmed on Weibo she had died the previous day due to an unspecified illness. Chow had just celebrated her 57th birthday on Dec. 6.

Zhou reportedly suffered from breathing difficulties on Sunday (Dec. 10) and was found unconscious at around 10 a.m. on Monday, per SET News. When she arrived at the Shunyi Branch of the Beijing Hospital of Traditional Chinese Medicine at 11 a.m., she had already lost all vital signs and doctors were unable to resuscitate her.

She had a history of hypertension and systemic lupus erythematosus. Doctors declared the cause of death to be cardiac arrest, loss of consciousness, and respiratory failure.

After finishing 15th in the Miss Hong Kong pageant contest in 1985, Chow made her entertainment debut as an actress in the TVB drama "The Yang's Saga." Over the years, she acted in many TVB TV series such as "The Feud of Two Brothers," "The Price of Growing up," and "Looking Back in Anger."
