Many things are not necessarily described in terms of eras, but are actually eternal. If I have a treasure and someone takes it away, is it permissible to say that it "belongs to a bygone era"? Don't I have the right to claim this treasure? If I have a precious monarchy, or a precious medieval feudal system, should it be said to be "outdated" because it is older than the bureaucracy?

The bureaucracy system existed in East Asia as early as the Qin Dynasty; the feudal system, as far as the East Asian timeline is concerned, the European Feudal Era and the Charlemagne Era were later than the Emperor Taizong of the Tang Dynasty. Is the feudal system an outdated thing? (The feudal system lasted in Japan until the Meiji Restoration, and in Tibet until the invasion of the CCP.) If I have a precious thing, don’t judge it by the era, but it is actually a modern thing，and it is an eternal thing. If you want to get it, it will always exist. Just like the word "Greece", it is a word that dates back thousands of years. However, the Greek kingdom became independent from Ottoman Türkiye. How can we think of the word "Greece" as an "outdated" concept?

Nothing is obsolete.

The British still call Deutsche German. The word German is a word from the Roman era, a word from the Roman period and the Tacitus period.

The republic existed in ancient Greece, and the ancient Greek republic was older than the British monarchy. Before the Kingdom of England was established, Athens in ancient Greece was a republic. The Republic of Athens was earlier than the British monarchy. How can we say that the republic is not "outdated" but the monarchy is "outdated"?

The bureaucracy of the Qin State was much earlier than the European feudal system. Why is the feudal system "outdated" but the bureaucracy is not "outdated"?

Many things are not limited to a certain era, but are actually eternal. If you want to get it, it belongs to your current era. Ask for it, strive for it, and it will appear in your time.

Just like the word "Greece", it is very ancient. However, after World War I, Greek nationalists did not think that the word "Greece" was an "outdated" concept?

When we look at the sun, moon, and stars, we don't think that their billions of years of history are bad; when we look at the rocks of the earth, we don't think that their millions of years are wrong... We don't consider their billions of years or millions of years of history to be incorrect, or something that should be replaced—what do we think?  We think that their billions of years of history, their millions of years of history, are incredibly magnificent. The sun, existing for billions of years, and the rocks, existing for millions of years, are awe-inspiring and venerable in their antiquity and longevity.  When we look at the sky, we don't think that the sun's billions of years of history are wrong; when we look at the land, we don't think that the rocks' millions of years of history are incorrect... Right? We don't think the sun is outdated, or the rocks are outdated.  So why should we think that a political system is outdated? A political system that exists for only a few thousand years, not even millions or billions of years—this system of a few thousand years, is it outdated? We don't think the billions-of-years-old sun is outdated, we don't think the millions-of-years-old rocks are outdated... Why should we think that a political system or cultural tradition, only a few thousand years old, is outdated? Many things aren't meant to exist only within a particular era... When we find something very ancient, we shouldn't necessarily replace it...

The British don't think their traditions and monarchy are outdated, and the Japanese don't think their monarchy is outdated... They take pride in their ancient traditions, and take pride in preserving and continuing them.
