我们在购买某件东西的时候一定都有过这样的思想：价格贵的东西一定就是****的。其实不然，我们的这种价值观到底正不正确，其实连我们自己都知道。因为不是所有贵的东西就一定是****的。
When we buy something, we must have such a thought: the expensive thing must be the best. In fact, it is not. We all know whether our values are correct or not. Because not all the expensive things are necessarily the best.

护坡模具有不同材料制作的，我们能说护坡钢模具价格高就一定是****的吗？塑料护坡模具价格便宜就不好吗？东西的好坏没有一定的定论。只是什么样的产品适合什么用。
The slope protection mould is made of different materials. Can we say that the high price of the slope protection steel mold must be the best? Is it not good if the price of plastic slope protection mould is cheap? There is no definite conclusion about the quality of things. Just what kind of product is suitable for what use.

塑料护坡模具和护坡钢模具是两种不同材料的模具，在选择购买的时候客户也会根据不同的使用环境，生产时间，工程的需要进行选择。塑料模具的好，由于价格低，表面光洁度好占据了优势。
Plastic slope protection mold and slope protection steel mold are two kinds of mold with different materials. When choosing to purchase, customers will choose according to different use environment, production time and engineering needs. Plastic mold good, because of the low price, good surface finish occupies the advantage.

钢模具的好，由于生产快，使用寿命长占据了优势。两种不同的模具虽然价格上悬殊很大，但是质量的高低单凭价格就下结论是****不理智的看法。
The good steel mold, due to the rapid production, long service life occupies the advantage. Although there is a big difference in the price of two different molds, it is totally irrational to draw a conclusion on the quality only by the price.
