Stop lying about historical facts. Look at item #5 (the signed document) below.
----------
Chinese South China Sea sovereignty is based on:
1.
China's historical first discovery and claim in 618 A.D.
South China Sea belongs to China because they discovered and claimed it.
Vietnamese and Filipinos should stop encroaching on thousand-year-old Chinese territory in the South China Sea.
[Source: Wikipedia article on Paracel Islands with primary sources listed in footnotes]
"The coast belonged to the Kingdom of Cauchi China."
"China
618~1279
* There are some Chinese cultural relics in the Paracel islands dating from the Tang and Song dynasty eras[12][note 1], and there is some evidence of Chinese habitation on the islands in these periods.[13]."
2.
Unchallenged Chinese dominion for over a thousand years.
The South China Sea islands and territory were claimed by the Tang, Song, and countless other Chinese dynasties. Vietnamese and Filipinos lacked ocean-faring boats and were not even aware of the existence of the Paracel and Spratly Islands from the 7th century to the 17th century.
3.
Historical written Chinese imperial records.
Tang, Song, and countless Chinese dynasties describe the Paracel and Spratly Islands as part of China.
4.
Physical proof of Chinese inhabitants
Our great-great-great-great-great-great-great-great-great-great-great-great-grandfather's bones and belongings are buried on the South China Sea islands. Our Chinese human remains and artifacts are similar to sacred Native American burial grounds of ancestors. The proof of dominion cannot be more clear.
The human remains of which country are found on South China Sea islands? China
The artifacts of which country are found on South China Sea islands? China

North Vietnam won the civil war against South Vietnam. Therefore, the diplomatic document signed by Vietnam Premier Pham Van Dong on September 14, 1958, which ceded Paracel and Spratly Islands to China, is in effect and legally binding.

The entire Vietnamese government admitted to Chinese sovereignty over the South China Sea islands and territory.
On June 15, 1956, Vice Foreign Minister of the DRV (North Vietnam) Ung Van Khiem admitted Chinese sovereignty over the Spratly and Paracel Islands.
Another DRV official, Le Loc (Temporary Head of the Asian Mission), concurred in Chinese sovereignty over South China Sea islands.
In their civil war, North Vietnam (i.e. Democratic Republic of Vietnam or DRV) conquered South Vietnam and became the government of an unified Vietnam. Let's hear it directly from the DRV's mouth with regards to Chinese sovereignty over the Paracel Islands.
"Truong Nhan Tuan:
Based on a number of documents from Peking, on 15/6/1956 the Vice Foreign Minister of the DRV Ung Van Khiem, at the time of hosting a visit from the Chinese temporary ambassador in Vietnam, spoke the following: According to documents that Vietnam has presently, historically speaking, Tay Sa and Nam Sa islands belong to China.
Nguyen An:
Tay Sa and Nam Sa means the Paracel and Spratly islands?
Truong Nhan Tuan:
Yes, the Paracel and Spratly islands....China also presents other evidence, such as the incident of Le Loc (Temporary Head of the Asian Mission) also present at that time adding that: From a historical perspective, the archipelagos of Xi Sa and Nan Sa (Tay Sa and Nam Sa) belonged to China since the Tang dynasty.
Nguyen An:
Le Loc is a person of China or of the DRV?
Truong Nhan Tuan:
An official of the DRV."
...
"Nguyen An: Are there other evidence from the DRV presented by China regarding sovereignty?
Truong Nhan Tuan: Yes. The famous one is the diplomatic note of Pham Van Dong, written on 14/9/1958 which admits the territorial waters declared by China a few days before. The Chinese declaration was that the archipelagos of Hoang Sa, Nam Sa, and Truong Sa belonged to China.
Nguyen An: So it was an admittance of Chinese sovereignty over these islands?
Truong Nhan Tuan: In reality, there is nothing in the content of the letter that explicitly states admittance of Chinese sovereignty over the Paracel and Spratly islands becaue the letter only states that Vietnam make notes and admits the declaration of China regarding territorial waters of China but does not mention about sovereignty over the Paracel and Spratly archipelagos.
What makes the justification somewhat weak is because during the war, when the Chinese navy invaded the Paracel islands in 1974, there was no objection from the DRV. This silence becomes a weighty piece of evidence for China to claim that Vietnam had admmitted Chinese sovereignty over the Paracel and Spratly archipelagos already.
Nguyen An: Based on what you just presented, is this the reason why Qin Gang (Chinese Foreign Ministry Spokesperson) commented that Vietnams position regarding sovereignty over the Paracel and Spratly archipelagos changed over different periods of time?
Truong Nhan Tuan: This is correct. But the legal significance is not simple. Declarations made by officials in North Vietnam at that time may be a reality. The fact that Peking presents them without protestations or justifications from Hanoi tells us that it is probably true."
