Retired nurse Su Qin spent all her life savings to buy a house for her son and daughter-in-law, and also received a monthly subsidy of 6,000 yuan. She lived frugally and devoted herself to the house for four years. She wanted to reunite during the Chinese New Year, but was rejected by her daughter-in-law because she had no room. When she turned around, she found that her son was welcoming his parents-in-law to move in. Frustrated, she decisively stopped the subsidy and took back the house according to the law with the help of the real estate agency agreement. After selling the house, she paid off the loan, started traveling around the world, and lived the second half of her life for herself. After the son and daughter-in-law lost their support, their lives were difficult, and they finally grew up through reflection, and the mother and son finally settled down well.
