We often see a lot of old people playing games under the shade of the chessboard, and we can see a lot of old people dancing in the community activity square, and we can also see old people with heavy steps, alone and sighing, and there are also old people who are closed, depressed and even suffering from depression. (1) Older people who have just retired, especially those in towns and cities, often feel that they have nothing to do after retirement, or feel uncomfortable doing anything, and are prone to feelings of loneliness and uselessness. (2)Older people who were leading cadres before retirement are used to the feeling of being surrounded by people before retirement, and after retirement, they are always in a kind of “people in the tea cold” feeling, which will inevitably produce a sense of loss, emptiness and confusion. (3) The elderly who are introverted and have few friends are reluctant to find someone to talk to when they encounter unpleasant things, and there is no appropriate object to talk to, so they cannot vent their emotions. (4) Older people who have no hobbies (5) Older people who are widowed (6) Older people with physical illnesses, on the one hand, they have to face the torture of the illness itself, and on the other hand, they tend to feel useless, inferior, and a burden to their families because of the increased burden on them. (7) Older people with low social support from their families (8) Family conflicts are obvious: the husband and wife are incompatible, the children are unfilial, and the older people in this environment often feel hopeless and hopeless about the future. (9) Older people with low education level and no knowledge of depression do not know how to manage and intervene in time at the early stage of the disease, and let the disease progress and easily develop into depression. Our population is getting older and older people, as a special group in our society, depression in old age is becoming more and more prominent, so our whole society should give full care and support to the elderly to prevent depression and let them enjoy their old age peacefully.
