What is the sentence of 420 years in western legal system?

We sometimes see in the news that criminals in some western countries have been sentenced for 300 years or more, and we feel very strange and laugh, and think that legislators in this country have no brains: how can a person live for 300 years or hundreds of years? Isn't this punishment meaningless? In fact, this is determined by the legal system and legal system of their country.

At present, the legal system in the world can be simply divided into two systems (some are divided into three systems and five systems), namely, the continental law system and the Anglo-American law system. The continental law system is characterized by written law. In other words, all laws and regulations are in written form, and the judgment is subject to the law, which can be found in written form. China belongs to the civil law system (also known as "Chinese law system"). The characteristics of Anglo-American legal system are not written laws, but based on previous precedents and judges' judgments. In this way, there is a difference between the two. Because the makers of statute law will make appropriate adjustments in advance considering the actual implementation and formulate rules that are in line with the actual situation. Anglo-American legal systems are different. It "sets" the current situation into the past precedent and applies it directly without selection or restriction. So sometimes there will be jokes that need to be imprisoned for thousands of years because of simple addition.

After you have a basic understanding of this legal system (and system), it will be normal for you to hear and see such a thing as 300 years imprisonment in the future.
