"I must come to rescue," said Wang, adding that the best time to assist a cardiac-arrest patient is within four minutes.

Wang said the sudden death of model-actor Godfrey Gao due to cardiac arrest during the shooting of a television in 2019, made him worry much about his mother, who has a heart condition.

He obtained certification for CPR and AED (Automated External Defibrillator) issued by the the Red Cross Society of China the same year. 

"As an ordinary Red Cross volunteer, I just did what I should do. I hope more people will learn the first-aid skills such as the use of CPR skills and the installment of AED devices, and participate in the public first-aid activities," he said.
