经济崩溃时应该做什么生意？

中文版：

在经济崩溃的时期，许多传统行业可能遭受重创，但也有一些行业会逆势而上，成为经济的避风港。那么，在这样的时期，我们应该做什么生意呢？

首先，生活必需品行业通常能在经济崩溃时保持一定的稳定。比如食品、饮用水、医疗用品等，这些都是人们在任何时候都需要的物品。因此，开设超市、药店或者提供基本生活服务的生意可能会更有保障。

其次，二手商品和循环经济相关的业务也有可能在经济崩溃时兴起。在经济困难时期，人们往往会更加珍惜资源，对二手商品的需求可能会增加。因此，开设二手商品市场、回收再利用等业务可能会受到欢迎。

最后，技术和创新也是值得关注的领域。尽管经济崩溃，但人们对于科技产品和服务的需求可能不会减少。因此，提供科技解决方案、创新产品或服务的公司可能会找到新的发展机遇。

What Business to Start in an Economic Collapse?

During an economic collapse, many traditional industries may suffer significant losses, but some industries will thrive and become havens for the economy. So, what kind of business should we start in such a period?

Firstly, the industry of daily necessities usually remains stable during an economic collapse. Items such as food, drinking water, and medical supplies are essential for people at all times. Therefore, businesses like supermarkets, pharmacies, or those providing basic living services may be more secure.

Secondly, second-hand goods and circular economy-related businesses are also likely to rise in popularity during an economic collapse. In difficult economic times, people tend to cherish resources more, and the demand for second-hand goods may increase. Hence, businesses like second-hand markets, recycling, and reuse may gain popularity.

Lastly, technology and innovation are also worth looking into. Despite an economic collapse, people's demand for technology products and services may not decrease. Therefore, companies offering technological solutions, innovative products, or services may find new opportunities for growth.
