相当长一段时间以来，许多商品在广告宣传和包装上都声明实行“三包”。在以卖方市场为主的时期，“三包”几乎成了消费者信任企业产品质号的一个尺度：只要实行了“三包”，便等于企业给消费者吃下了一赢定心丸。许多人也觉得，有了“三包”，总比那种东西没用上几天就坏了、 For a long time, many products in the advertising and packaging have stated that the implementation of “Three Guarantees.” In the period dominated by the seller’s market, the “Three Guarantees” almost became a yardstick for consumers’ trust in the product quality of their products: as long as the “Three Guarantees” were implemented, it would be equal to the enterprise giving consumers a win-win solution. Many people also think that with the “Three Guarantees”, it is always worse than not spending the last few days with that kind of thing.
