During the first two decades of their development, convenience stores mostly dealt in the basic material ingredients of modern daily life: drinks, newspapers and magazines, instant noodles, junk food, frozen foods, cigarettes, and the like. Though they did offer hot food, this was limited to easily heated-up items like hot dogs, baozi (stuffed steamed buns), and the omnipresent pot of hard-boiled "tea eggs."
在發展的前 20 年，便利商店經營內容多以飲料、書報、泡麵、零食、冰品、香菸等民生必需品為主，雖然也有熱食，但僅限方便處理的熱狗、包子、茶葉蛋。
