The real economy refers to those economic activities that realize material transformation and value transformation in the production process. Typically, when 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 transformation and value increment.

Virtual economy refers to all economic activities that directly aim at "Qian Shengqian" without actual production, value conversion and value creation, and its return on investment is purely from the rise or fall of asset prices themselves. For example, buying and selling house property rights, buying and selling stocks, government bonds, corporate bonds, futures, options, foreign exchange directly targeting banknotes of various countries ... In addition, it also includes gambling, art collection and other industries.

Economy = real economy (trade in goods and services)+virtual economy (trading in financial assets)
