俗话说：三十年河东，三十年河西。人生确实如此，大起大落，变化无常。本来是站在同一起跑线上的朋友，经历人世沧桑之后，有的高官厚禄，腰缠万贯，有的却落魄江湖，举步维艰，形成对比鲜明的巨大反差。在这种情况下，往日的贫贱之交如何继续来往，成为从古到今的热门话题。 As the saying goes: Thirty years Hedong, Hexi three decades. Indeed, ups and downs in life, changeable. Originally standing on the same starting line of friends, experienced after the vicissitudes of life, some senior officials, wealthy, and some have gone downhill, struggling to form a sharp contrast to the huge contrast. Under such circumstances, how to continue the past and present between the poor and the common has become a hot topic from ancient times to today.
