50年代,我家住在上海乡下小镇上,回想小时候常常拿了妈妈给的几分零用钱去南货店买炒花生吃。那时候的南货店是用黄草纸(用稻草制作的很粗糙纸张)来包装花生、红枣和糕点之类食品。店里伙计能熟练地用纸将花生包成三角形,故名三角包。这些黄草纸丢弃后还可作为农家肥料,回归大自然,十分符合环境保护。到了80年代,开始使用塑料薄膜口袋,那时候上海一些店家还舍不得使用塑料袋,顾客非要不可,那末需交几分钱。可是到了90年代,你就是买几棵青菜,农民兄弟也 In the 1950s, my family lived in a small rural town in Shanghai. When I recalled a child, I usually took a bit of pocket money from my mother to buy fried peanuts in the southern department store. At that time the South goods shop is to use yellow grass paper (straw made of very rough paper) to package peanuts, dates and cakes and the like. Shop guy can skillfully use paper to wrap peanuts into triangles, hence the name triangle bag. These yellow grass paper can also be discarded as a farm manure, return to nature, is in line with environmental protection. By the 1980s, the plastic film pockets began to be used. At that time, some stores in Shanghai still reluctant to use plastic bags. Customers should pay a few cents. But by the 90s, you just bought a few green vegetables and peasant brothers too
