Extended information:

The effectiveness of law on persons has been adopted in the legal practice of various countries around the world. Four principles of effectiveness on persons have been adopted:

① Humanism means that the law only applies to citizens of the country, whether they are at home or abroad; it does not apply to non-citizens even if they are in the country.

② Territorialism, the law applies to everyone within the jurisdiction of the country, regardless of whether they are citizens of the country, they are bound by the law and protected by the law; if the citizens of the country are not in the country, they are not bound and protected by the law of the country. .

③Protectionism means safeguarding national interests as the basis for whether to apply national laws; anyone who infringes on national interests, regardless of nationality and location, must be held accountable by the laws of that country.

④ Focus on territorialism, combined with personalism and protectionism. This is the principle adopted by most countries in modern times. The same is true in our country. The reason for adopting this principle is that it is necessary to not only safeguard the interests of one's own country and uphold its own sovereignty, but also respect the sovereignty of other countries and take into account the practical possibilities in the application of law.
