before the Spring Festival of 2002, the two daughter who worked in Beijing moved into a new house, which reserved a bedroom for our old couple. His wife lives in a daughter’s family. At that time, I was still working in Xinjiang, and I went back to Beijing to visit my family for the new year. The old wanglao couple who lived in Zaozhuang, Shandong, heard that when I returned to Beijing for the new year, I came to visit us from my hometown in Shandong. First meeting, mutual respect and hospitality, harmonious relationship, leaving a good impression. Despite his ill health, his wife insisted on buying vegetables and cooking, and warmly entertaining his relatives in his own capacity. After that, Shandong’s relatives often call us to visit Zaozhuang. Because I have not yet retired, my wife is ill, and failed for several years.
