Brothers, if you had even one more front tooth, you couldn't sing the sorrow of widows, the helplessness of welfare recipients, the loneliness of bachelors, the regret of remaining women, and the grievances of married women. Men listen and go crazy, women listen and stop their periods. At first, it sounds heartbreaking, then it sounds hopeless. Not only does it sing the longing and helplessness of village welfare recipients for widows, but it also sings the reluctance of retired old cadres for their secretaries. It shows the hardship of the poor, the anxiety of the rich, the exhaustion of the strong, the helplessness of the weak, the worries and confusion of the wise; depicts the innocence of children, the naivety of teenagers, the passion of youth, the steadiness of middle age, the vicissitudes and openness of old age. In this life, there are only two words that people can't let go of: love and money. People get up early and stay up late for money, pour their hearts out for love. In the end, money can't be taken away, love can't be kept. Life is like a play, entering dreams is life, waking up from dreams is the end of the show. A song not only sings the darkness of human nature and the various states of society! But also sings the pain that even ibuprofen can't stop! It also sings the wounds that Yunnan Baiyao can't heal! And the worries that enema solution can't resolve...
