在这个世界上，没有一个地方不存在经济生活。无论是美国、中国这样的大国，还是热带丛林中只有几十个人的原始部落，都离不开经济生活。我们天天与经济打交道，唯有了解经济学常识，善于应用一些经济理论，才能让生活更加有声有色，有滋有味。要知道生活处处是经济，懂经济学的人才懂生活；生活处处是经济，懂经济学才能创造更多财富。In this world, there is no place without economic life. No matter in big countries like America and China or in primitive tribes with only dozens of residents in tropical jungle, no body can survive without economic life. We get along with economics every day. As long as we get to know some common sense of economics and we are good at making use of some economic theories, our life will be more colorful and interesting. Economics is everywhere and people who know economics can create more wealth.
