The text I posted is from the 欽定大南會典事例 which was compiled during the Nguyen dynasty.
These non-Han emperors claimed to be Chinese and held sacrifices to honor the previous dynasties,I don't need to go over this again the Yuan,Qing etc all claimed to be rulers of Zhongguo.
Look at Qing era treaties,the Great Qing is synonymous with China.
The 大越史記全書 has many flaws that cannot be glossed over.
Regardless I'll go over the claims over and over again until Vietnamese nationalists stop pestering me.(My Japanese published copy of 大越史記全書 dates to 1868 so expect some minor discrepancies.)
1.There's no archaeological evidence of the existence of Hung Kings or Van Lang,there's no point in me asking for them as no one ever presents them.
2.都峯州。The capital was situated in Fengzhou.

The usage of the word zhou(州) in this context is a Sui-Tang naming convention,therefore Fengzhou is an anachronism.

3.其國東夾南海。西抵巴蜀。北至洞庭湖。南接狐猻國。卽占城國。今廣南是也
To the east it bordered the southern sea,the west Ba Shu, to the north Dongting Lake and to the south Hu Sun(Champa),which is present day Guangnan province(Le dynasty).

according to 欽定越史通鑑綱目:洞庭地夾兩湖實在百粵之北巴蜀猶隔雋滇(今屬雲南) 不相接壤舊史侈大其辭殆與後蜀王之事皆屬傳虛而未之。
Lake Dongting is situated between the two Hu's ie Hunan and Hubei. Lake Dongting is North of the Baiyue. Ba and Shu were separated from Van Lang by Xi and Dian(both located in modern day Yunnan),thus Van Lang did not share a border. The old texts are obviously exaggerated. Furthermore this and King Shu Pan are not credible and have never been substantiated.
考也況所分十五部皆交阯朱鳶以內全無一部在北可證其誣也
The demarcation of the 15 regions are within the lands of Jiaozhi and Zhuyuan,not a single piece of land is north of these areas.

This phrase is used in the Huayang Guozhi showing that it is just a mimicry.

4..分國為十五部。曰交趾。曰朱鳶。曰武寧。曰福祿。曰越裳。日寧海。曰陽泉。曰陸海。曰武定。曰懷驩。曰九真。曰平文。曰新興。曰九德。
Van Lang was divided into 15 commanderies:Jiaozhi,Zhuchuan,Wuning,Fulu,Yuechang,Ninghai,Yangquan,Luhai,Wuding,Huaihuan,Jiuzhen,Pingwen,Xinxing,Jiude.

欽定越史通鑑綱目 even has passages that claims those commanderies were all located in Northern Vietnam not Southern China.
山南 (今河內南定興安地是) 古交阯部
Jiaozhi commandery was located in Shannan(Nguyen era Henei,Nanding and Xingan).

5.嶺南摭怪 is the basis of the the Hung King myth,yet the region Lingnan is a far larger area then Northern Vietnam,the Han and ethnic minorities of that region don't recognize this myth.
6.Texts dating to the warring states and Han dynasty fail to mention Van Lang.
You claimed the information about the Hung Kings was taught in previous dynasties when 大越史記 doesn't even contain this information.
There's no mention of Hung Kings in the Shiji,neither did Sima Qian claim that Chinese can only be descended from Huangdi.
Plenty of surnames trace their ancestry to Yandi/Shennong including the Jiang(姜),Lu(呂),Xie(謝) etc tell me are Jiang Ziya,Lu Bu and Xie An all Vietnamese?
