The economic crisis is characterized by problems in economic operation, increased market risks and more bankrupt enterprises; If you buy stocks at this time, you may lose all your money; National debt is a risk-free investment, although the return is low but the security is high, so in order to avoid risks, we will naturally buy national debt. The increase of national debt by dozens of times usually only occurs in novels. Even if there is, it is also a period of war in history. The government issued treasury bonds at low prices in order to borrow money to fight the war. After winning, the price of national debt will rise, but not dozens of times.

China's current national debt is basically the same as that of western countries.
