几年“身无分文”的我看到瑟瑟发抖，看来以后还是需要备点现金啊。
"Being penniless" for several years, I'm shivering at this news. It seems that we still need to store some cash at home in the future.
其实，就是一旦我们突然因为不可控因素陷入原始社会状态时，我们要准备好如何应对。其实不止现金，粮食饮水储备也要学学日本家庭的做法，家里存够至少一个月的超超长保质期食物和饮水，日用品，并且记录更换日期。
In fact, once we suddenly fall into primitive society because of uncontrollable factors, we should be prepared to deal with it. In fact, not only cash, but also food and drinking water , we should learn from Japanese families who store at least one month's supplies of food, drinking water and daily necessities with super long quality guarantee period at home, and they will replace these things according to their quality guarantee period.
