What is the meaning of epidemic special national debt?

In the recent news, the epidemic special national debt began to move towards everyone's sight. So what is this? What is the impact on the whole society? Please look down. What does the epidemic special national debt mean? The special national debt for epidemic situation is used as a protective cushion for this epidemic situation. It is generally used for hedging against financial crisis and sovereign credit crisis, and for post-disaster recovery of some natural disasters. Because it is not used to make up the deficit, but to improve the level of foreign exchange business income, it is also called special national debt. The first special national debt was issued in August 1998, with a scale of 27 billion. Its purpose is to supplement the capital of the four major banks and prevent systemic financial risks. It happened to be the Hong Kong financial turmoil in 1997. After three rounds of contests, China announced the official victory over Soros on August 28th, 1998. In 1998, the special national debt was issued in August. Obviously, this is the key to winning. The second issue was issued in August 27, with a scale of 155 million, which was used to purchase 2 billion US dollars of US Treasury bonds. However, it is not directly bought from the United States, but from the central bank. Because the special national debt is not included in the fiscal deficit, it essentially takes away part of the central bank's foreign reserves, which reduces the scale of the central bank's foreign reserves and prevents the rapid increase of foreign reserves from being forced to release a large amount of liquidity. This special national debt is undoubtedly for the sake of the COVID-19 epidemic, so it is called the special national debt for the epidemic.
