He called the system "an entirely new political system that has grown from Chinese soil," hailing it as a great invention in the evolution of political institutions in human history.

The NPC is China's highest organ of state power. The first session of the first NPC was convened In September 1954.

The establishment of this system marked a profound transformation in China's political landscape, signifying a shift from a system where the power was concentrated in the hands of a few while the majority faced oppression and exploitation, to one that empowers the people to govern the country as its masters under the Party's leadership, Xi said.

Over the past 70 years, the system of people's congresses has demonstrated its clear political strength, providing an important institutional guarantee for creating miracles of rapid economic development and long-term social stability, Xi noted.

It is a sound system that embodies the country's socialist nature, he said.

Noting that the system of people's congresses is an important institutional vehicle for realizing whole-process people's democracy in China, Xi said it is imperative to uphold the CPC's leadership and adhere to using institutions to ensure that the country is run by the people.

He stressed the need to give full play to the role of people's congresses in ensuring full and effective implementation of the Constitution and laws.
