Abstract: With the arrival of the era of population aging, perceived psychological contract breaches, such as mutual blame and complaint as to life attitude, interactive mode and social priority, have appeared between the aged and the youth in the Chinese context. This situation calls for the construction of a harmonious intergenerational psychological contract. Under the perspective of positive psychology, three approaches might be followed. The first is to build a positive social environment that favors the welfare for the aged. The second is for both the aged and the young to form a positive personality. And the third is to experience happiness in social interaction. In this way, a harmonious relation between the aged and the young can be developed.
