Second-hand junk generally refers to buying used goods or cargo.The used relative to the primary goods are not sold and used.Most used goods once are used, so the price will be lower than the new item, such as second-hand cars.But there are exceptions, such as works of art or limited edition items like collectibles.These collections are not used, therefore the second-hand prices may be higher than the primary prices, just like antique tables.

　　二手商品一般是指购买使用过的商品或货物。使用过的与没有出售过和用过的初级产品是相对的。大部分二手产品都是使用过的，所以价格会比新的要低，如二手车。但是也有例外，如工艺品或限量版的商品，就像收藏品一样。这些收藏品没有用过，因此，二手价格可能会比原价格要高，就像古董表。
