The recovery rate was 66.36%, of which 3 602 valid questionnaires were from IP in Hunan Province, and the qualified rate was 82.71%. Among the subjects, 1 532 were men (42.53%) and 2 070 were women (57.47%). The majority aged group from 19 to 30 (59.41%) and from 31 to 50 (36.70%). 307 were rural (8.52%) and 3 295 were urban (91.48%); and the majority levels of education were senior or technical secondary school (38.26%) and undergraduate or junior college (44.50%).

Among these people, the correct rate was higher in the ages of 31-50 years old and ≤ 18, 19-30 than those ≥ 51 years old (12.71% vs. 0%, 6.87%, 8.70%, χThe public in Hunan Province have a strong sense of first aid, and some of the theoretical knowledge of CPR.
