The research shows that: ① in the intergenerational family tourism, recalling experience and sharing experience after traveling have a significant positive impact on the tourism satisfaction of the elderly; ② recalling and sharing experience and tourism satisfaction have a significant positive influence on the life satisfaction of the elderly; ③ tourism satisfaction functions as a mediator in the impact of recalling experience and sharing experi? ence on life satisfaction of the elderly; ④ the comparison of the data analysis results shows that recalling experi? ence can more effectively improve the tourism satisfaction of the elderly, and sharing experience can better the life satisfaction of the elderly more significantly. As an important way of filial piety expression and intergenera? tional interaction, intergenerational family tourism can not only enrich the spiritual life of the elderly, but also improve their life satisfaction in the process of sharing and recalling this experience after traveling.
