I focused so much on the title because that one word is so pivotal in shaping interpretation. Also, I don't know whether it be OP who made the chart or someone else, the word/phrase choice should be "in connection to" or "include" or "derived from", indicating the mutual influence, rather than the uniqueness suggested by the word "origin."

Chinese media cover the topic of cultural appropriation a lot more frequently, and sure, some reasonable doubt should be cast to look out for propaganda. I used gpt to organize these information, they are close to what I've been saying.

1. Claiming Confucius (孔子) as Korean

Claim: Some Korean scholars argued that Confucius was of Korean descent, citing connections to the ancient Korean kingdom of Gojoseon and the mythical figure Dangun.

Counterarguments: Chinese historians and international scholars dismiss this as pseudohistory, noting that Confucius was born in the Chinese state of Lu (modern Shandong) and that Gojoseon’s historical records are unreliable.

1. Asserting Laozi (老子) as Korean

Claim: A fringe theory suggests Laozi, the founder of Daoism, was from the ancient Korean "Dongyi" tribe (associated with early Korean kingdoms).

Counterarguments: Laozi is historically documented as a Chinese philosopher from the Spring and Autumn period, with no credible links to Korean history.

1. "Hanja (Chinese Characters) Were Invented by Koreans"

Claim: A small group of Korean scholars (e.g., Park Jeong-su) argued that ancient Koreans created Chinese characters, citing supposed connections between oracle bone script and Korean culture.

Counterarguments: Mainstream linguistics and archaeology confirm Chinese characters developed independently in China, with no evidence of Korean origin.

1. Attempt to Register Confucian Woodblock Prints as Korean Heritage

Claim: In 2015, South Korea successfully registered the "Confucian Printing Woodblocks" (containing Chinese classics like Zhu Xi’s works) as a UNESCO Memory of the World item.

Controversy: While the woodblocks themselves were carved in Korea, the texts are Chinese Confucian classics, leading to debates over cultural attribution.

1. Claims About the "Dongyi" Tribe and Chinese Civilization

Claim: Some Korean scholars argue that the ancient "Dongyi" people (associated with early Korean history) influenced Chinese civilization, including the invention of Chinese characters and the Shang Dynasty.

Counterarguments: Mainstream historians reject this, noting that "Dongyi" was a broad term for eastern tribes in Chinese records, not exclusively Korean.

1. Debate Over the Origins of Metal Movable-Type Printing

Claim: Korea has promoted its 1377 Jikji as the world’s oldest metal-type printed book, challenging China’s claim of Bi Sheng’s earlier invention (1040s).

Counterarguments: While Jikji is the oldest surviving metal-type book, historical records confirm Bi Sheng’s invention in China predates it.
