This table entry uses the wrong surname character for the ruling house of Yan (燕).

Primary and standard historical accounts identify Yan's founder as Shao Gong Shi (召公奭), who shared the Zhou royal surname Ji (姬). The Shiji chapter on Yan states plainly: 「召公奭與周同姓，姓姬氏。周武王之滅紂，封召公於北燕」 — i.e., the Duke of Shao shared the Zhou surname Ji (姬) and was enfeoffed in Yan.

So the article's use of 姞姓 is not just an alternate spelling; it is a different surname character from the one used for the Zhou royal house and Yan's ruling lineage.

This dates Yue's fall far too late and attributes it to the wrong conqueror.

The state of Yue (越) had already ceased to exist as an independent Warring States polity long before Qin's final unification campaigns. A standard historical summary from ChinaKnowledge states that Yue "was in the end conquered by the state of Chu" and gives 333 BCE as the year Yue was conquered by Chu and Qi.

Likewise, standard overviews of Qin's unification list the states Qin defeated as Han, Wei, Zhao, Chu, Yan, and Qi. That is, Qin unified China by defeating the six remaining major rivals; Yue is not among the states conquered in 222–221 BCE because the old state of Yue had already fallen earlier.

There were later Baiyue / Yue peoples in the far south whom Qin campaigned against after unification, but that is a different matter from the Zhou-era state of Yue discussed in this article.

The table gives Yue's existence as "前2032年 - 前222年", but the end date is incorrect.

Standard histories place the end of the state of Yue (越) in the 330s BCE, when Yue was conquered by Chu (often dated 334 or 333 BCE), not in 222 BCE. By the time Qin was completing the unification wars, the old Zhou-era state of Yue had long since disappeared.

So even if the table is trying to include legendary early origins, its closing date of 222 BCE is historically wrong for the state of Yue described here.

The sentence is false because it lists Yue (越) as one of the states still surviving at that point.

But the Zhou-era state of Yue had already been eliminated in the 330s BCE. Historical summaries place Yue's fall under Chu (often with Qi involved), around 334/333 BCE. That means Yue was not one of the states still surviving in the late 3rd century BCE when Qin was moving toward final unification.

Standard summaries of Qin's last conquests likewise name Han, Zhao, Wei, Chu, Yan, and Qi as the principal states defeated in the unification wars, not Yue.

This sentence gives the end of the Spring and Autumn Annals (春秋) too late.

Reliable references place the annals' coverage earlier than 477/476 BCE:

• A Columbia University Tang Center description of the text says the Spring and Autumn is an annals text covering 722–479 BCE.
• A standard overview of the period states that the annals' first entry is 722 BCE and its final entry corresponds to 481 BCE.

So while there is some variation in modern references over whether one counts the text's endpoint as 481 or 479 BCE, the article's specific claim that the record ends in 477/476 BCE is not supported by these standard datings.
