Business cycles are not merely fluctuations around some smooth trend, but are instead the result of fundamental shocks to the economy.
经济周期不仅仅是围绕某个平滑趋势的波动，而是经济受到根本性冲击的结果。
我是一个不断进步的作品。
Concrete can be as warm as wood when it captures light.
If you want real peace in the world， start with children.
写作是面对存在的混乱并在其中找到意义。
