Descriptive statistic analysis shows that in the CLHLS, the elderly spiritual demand and supply is in a state of disequilibrium in our country, supply is far less than demand. The main factors of restricting the old people's spiritual need are not being met, including economic factors, intergenerational relations factors, emotional factors and the particularity of spiritual demand, etc. So we need to change our ideas, with the demand of the old structure and strength, by constructing a complete supply system of family, society and government to strengthen for the supply of the spiritual needs of old people, so that the elderly would be happy during his or her later lives.展开更多
