Harmonious and stable family relations are undoubtedly an important component of victory in terms of epidemic prevention. Take the COVID-2019 (2019 new crown pneumonia epidemic) as the major public events background; 24,188 national samples were obtained based on a network survey. We selected gender, education level, occupation type, family scale, neighborhood relationship and psychological state as independent variables, and adopted multiple logistic models to assess the impact of major public events on family relationships and the characteristics of humanistic-regional attributes. The findings are as follows: (1) During the epidemic period, major public health emergencies effectively promoted the national residents' family relationships. (2) The family relationships of national residents presented a high level in central China and a low level in the border areas of China, which is consistent with the spread of COVID-2019 in January and February. (3) Family relationship level averages between 2.201~2.507 among different groups when divided by occupation, age and education. The family relationship has improved, but the change is not drastic and the gap between various groups is not significant, so there is essentially no difference. (4) The impact of major public health emergencies on all families is nearly sudden and instant, so that family relationship changes are often also abrupt. (5) Educational level, family size and gender have a positive effect on the change in family relations, but this effect is weakened as family education level increases; while the anxiety of the interviewees and the neighborhood had a negative effect on the change in family relationship, this indicates that the better the neighborhood relations are, the more harmonious a family relationship is. The above research can provide an important scientific support and decision-making basis for the government to carry out community prevention work, respond to major public health emergencies and construct a family support social policy system in the future.
