The real economy refers to those economic activities that realize material conversion and value conversion in the production process. The most typical example is that if you build a factory to produce shoes and hats, you must convert the corresponding labor, real estate, various raw materials, and energy into goods that others are willing to buy. The money you earn comes from material conversion and value appreciation. Virtual economy refers to all economic activities that do not engage in actual production, do not participate in value conversion and value creation, but directly "make money from money", and their investment returns purely come from the rise or fall of the asset price itself. For example, the buying and selling of house property rights, stocks, treasury bonds, corporate bonds, futures, options, and foreign exchange transactions directly targeting banknotes from various countries... In addition, it also includes the gaming industry, art collection and other industries.

The total amount of economic activities in contemporary human society can be expressed as follows: economy = real economy (trade of goods and services) + virtual economy (financial asset transactions)
