经济学上说,商品价格一般会随市场供求关系的变动而变动。商家就是市场供求关系的观察者,是判断商品变动的直接推手。这些是一些经济学书上说的,但作为老百姓,咱们不关心那些书籍叙述的如何天花乱坠。老百姓只认一个死理儿,只要市场上哪类产品让咱们得到实惠,咱们也就认准了谁,就去捧捧谁的场。 In economics, the price of commodities generally varies with the supply and demand of the market. Business is the observer of the market supply and demand, is to determine the direct push of commodity changes.

Ordinary people only recognize a dead child, as long as what kind of products on the market so that we get benefits, we also look for who, go to hold who the field.
