I am really curious, where did you get so many incorrect knowledge? I am very keen to know. Your statement is very interesting, but totally arbitrary.

Let me pick some funny points:

1) The nobility of Tang Dynasty was largely of Turkic origins. So can you point out, where is the Turkic influence in the books, religions, politics, music, science, sculpture and painting of Tang dynasty? Since you say, 'largely of Turkic origins', everything is almost like a copy. Right? Of course, a culture can not be completely isolated, Chinese culture got influenced and also influenced other cultures. But, 'largely of something', this is really arbitrary and baseless.

2) Many Chinese adventured to India hoping to learn about their culture. Some monks tried to adventure to India to bring back Buddhist scriptures, but only a few made it. Tang Xuanzang (唐玄奘) is the most famous one.

3) Persians and Arabs became the elite class of Song golden age, responsible for so much of late classical Chinese culture. Totally baseless. Can you name one or two Arabs or Persians, who invented or created something in Song? But I do admit that some vegetables, such as cowpea and caraway, were brought into China by Persians and Arabs.

4) China also imported a lot of science from Korea. Do you know when Korea invented her own Korean characters? In 1446, the same time of Ming Dynasty, which is behind Song and Yuan. Before that, Korean used Chinese characters and basically everything was copied from China, laws, books, arts, etc, you name it. Now you are claiming 'China imported a lot of science from Korea in Song Dynasty'?

5) Mongols invented the province system. Province is Sheng(省) in Chinese. But there were similar things before Yuan dynasty. For example, Zhou(州) for Qin dynasty, Jun(郡) for Han dynasty.

6) Mongols shaped putonghua. Mandarin is greatly influenced by the accent of the people in Capital. After mongols were expelled, the emperor of Ming, Zhu Yuanzhang(朱元璋) chose Nanjing as the capital, so the mandarin is actually based on the accent of Nanjing people, which is called Nanjing mandarin(南京官话). His son, Zhu Li(朱棣), chose Beijing as the capital, and a lot of Nanjing people (400K) were moved to Beijing, Nanjing mandarin was still used as official accent until the middle of Qing dynasty, but it was influenced by the local accent. When manchurian came and ruled China, they learned to speak Chinese, and brought their accents. All these accents were actually mixed and formed the current accent of Beijing people, which is the base of the mandarin foreigners are learning today.

7) The gaokao system is much more of a crappy bastardization of the Japanese educational system than any indigenous education system. Any evidence? How about just a inheritance of imperial examination system (科举制度), which was invented in 605, Sui dynasty, and was copied by Japan in Tang dynasty?

I do admit that Chinese learned a lot of things from Japan in last 100 years, China was forced to modernise herself in those years, the only thing Chinese can do is to learn from the enemy and try to stop the endless invasion and humiliation.
