The question then becomes where do you draw the fine line?
Practically, entire western culture is a decedent of greeko-roman culture. To the point where the Holy Roman Empire (Germany) thought that it was the 2nd rome, that the Russian Empire considered itself the third Rome. alternatively, Asian culture (I am using it in the classical term), middle eastern culture is a direct decedent of the Persian and Babylonian cultures, yet no one after claimed to be the recarnation of the prior although they share the same culture, language and heritage.
Japan is an interesting question, genetically Chinese and Japanese are more or less identical; but I doubt that you will find people form either nation who willingly believe they are the same as the other. But Why I bring up Japan, and likewise Korea and Vietnam is that; during the fall of China, they thought themselves as the continuation of the "chinese essence" just as HRE and Russia had after the fall of rome. What more is, Japan also took the idea of mandate of heaven for their emperor; and like China, had used that mandate to shift power many times.
I am from HK, you can ask a person on the street who they feel they are and 50% of the time, you will get an answer that they are HongKongness while the other half will reply that they are chinese. As I am currently in Mongolia, infact I will be beaten up by neo-nazi skin heads if I suggest that they are Chinese - but you get Chinese styled temples and paintings etc. When I was in Tibet, Tibetans didn't really consider themselves Chinese either
So it is a much more muddled question; China is like Russia. It is much more like a country born out of the carcass of an empire and within it's borders are a diverse people who may not consider themselves as a part of the host country even thou they reside in it and share the same cultural heritage.
I hope you are NOT serious about comparing western culture to Chinese culture my friend.
Entire western culture is a decedent of greeko-roman culture, but it is only a descendant from learning from the books and conquest, there is no direct linage between Western culture at all, the closest connection is between Roman and Greeks, mostly because Rome learn from the Greeks mostly because they defeated the Greeks and colonize them and learn a lot from Greek slaves they employed.
And please tell me you are joking about the Holy Roman Empire, they were NOT Rome in any way possible, culturally or generically, I think the catholic church itself actually have more tradition from Rome than the Holy Roman Empire itself, they were nothing more than just a bunch of a loose feudal kingdoms that have this fantasy they were the 2nd Rome, but no they were NOT in anyway ship resemble Rome.
Voltaire sum it up nicely about them. "This agglomeration which was called and which still calls itself the Holy Roman Empire was neither holy, nor Roman, nor an empire."
There is no way in hell you can compare them to Chinese dynasty, if you do, you are either extremely delusional, or you really REALLY need to back to the history books.
Same thing goes for Russia, heck or even the Turks, everyone wants to be Rome after the fall of Rome, but it does not make it so, just because I think Jack Liu is the descendants of Liu Bang does not make it true. Because if there is no physical, no archaeological, no historical evidence there is NO connection. However all Chinese dynasty are connected from each other physically, there maybe much chaos in between but the time of unification is way longer.
Oh and yes, seriously dude Middle East empires??? Connections??? do you even know any history at all??? The earilist empire in middle east the Babylonian, the Assyrian Empires have NOTHING to do with the descendant empires, totally different culture, different people, different custom, different religion, different view of the world. Let's just take a look at religion, Babylonian practice Chaldeans, the Achaemenid Persian Empire practiced the famous Zoroastrianism, after their conquest by the Greeks, they introduced Western pagan religions, and well as Buddhism from India. After their conquest by Rome, a little was changed because region was similar, but then the native Parthian/Sassanid Empire broke away and took charge, they then have their own new religion again... Then comes the Islam invasion from East and introduced Islam and washed away everything else. I hope you can see the pattern here, there is THERE IS NO PATTERN, the only pattern is that they live on the same land, and occasionally one empire claim they are the descent from the other empire, but everyone else include they themselves knows they were not, they only claim so because it make them feel good, give them legit rule and strengthen their political power. And don't even let me trace their spoken/written language through out the time, you will not like what you see.
Can you say the same about the Chinese empires? They have surprisingly homogeneous culture all the way back from 2000 years ago, If I have a time machine and went back to the Han dynasty, I would not feel like I am visit an alien culture, however the same cannot be said for a modern Egyptian to go back to the Pharaohs days.
Show me another culture who have something remotely similar to this.
I'm sorry for the long response, but when you know nothing about what you talking about and randomly throw out terms like "Holy Roman Empire, Babylonian, Persian etc..." and try to make it stick, you just open up a whole can of worms, next time please go into deeper and explain your example rather before throw out names which DOES NOT support what you trying to say.
sigh...
Ok, lets move to Japan. Japan's so call "mandate of Heavy" is NOTHING like China's mandate of Heaven, in fact I don't even think they have one, the emperor itself rare have any power, it think itself too good to involve itself in politics, it was nothing more than a figure head while the real power is in the hand of various warlord and shogun. And the example of Vietnam and Korea that they so uphold Chinese culture is not because they want to be Chinese, because they have been so influence by Chinese culture that they want to hold on to their own culture, which at the same time is the Chinese culture.
And NO the China did not fall, it never fall, it is always there it just got weakened, and no, Vietnam and Korea never once said "We are the new China now" I have no idea where you are getting this from. It seems you just want to support your thesis that China is same as Rome, so whoever happen to Rome, happen to China. Which again.. totally bull.
So you are HKer huh? Good for you, please educated me what is HK culture base on? How long does this HK culture date back? What language does HKer speak? Where is HK language come from? What holiday does HK people celebrate? What food does HK people eat?
HK identity is not a culture identity, it is a regional identical, must like Shanghainess identity or any other dozens of China's regional identical, you guys are as Chinese as your bothers and sisters across the river, only differences is you feel you are rich and successful that you snub everyone, that you feel you are superior solely due to your wealth, but hate to break it to you brother, you are the same as the rest of 1.3 billion people no matter how superior you are or how different you feel. Answer me honest, in 1000 years, how strong do you think the HK identity will be? In fact I won't be surprised if people are studying HK history from the history archives.
I already said in my earlier post that Tibet and Uygur and Mongolians don't consider themselves to be Chinese, because they are relatively new conquest by the Chinese civilization, thus they feel the need to rebel, but you, yourself have listed dozens of other races in the past being conquered by Chinese civilization, and look what happen to them? They were all integrated into the Chinese civilization didn't they? I'm sure at the time of conquest, they felt as strongly as Tibetan/Uygur /Mongolians feel today. But record speak for itself of what happened to them.
And NO China is not like Russia, and the example you give was the USSR, who's half of their populations consider themselves none Russians, and the break of of USSR solve the problem, nowadays majority of people in Russia consider themselves to be Russian, and yes the majority of people in China consider themselves to be Chinese as well. Notice I said "Chinese" not "Han"
Please in your next reply, go deep into your each example and expand upon it, you can't just throw out stuff like firing a shotgun and hope something will hit.
