"我们政治制度的基础是人民制定和修改其政府宪法的权利。"

Simplified Meaning:

The heart of our government's system is that people have the power to create and change the rules that govern them. Imagine you and your friends make a set of rules for a game. Over time, you realize some rules aren't fair or don't work well, so you and your friends decide to change them. Similarly, in a country, citizens have the right to decide how their government works and to change it if they think it needs improvement. For example, in history, the U.S. Constitution was created by people who wanted a fair and just system. Later on, as society evolved, amendments were made to address issues like voting rights and equality. This ongoing process ensures that the government continues to reflect the people's needs and values. To apply this idea in everyday life, remember that you have a say in how things are run, both in small groups and larger communities. By participating, voicing opinions, and voting, you help shape the rules and make sure they stay relevant and fair for everyone.
