Recent findings (audit lane, verbatim)

Guanzhong — The surrender of the last Qin ruler (Ziying) occurred in 207 BC, not 206 BC.

Guanzhong — Liu Bang's reconquest of the Three Qins began in 206 BC but was completed in 205 BC; stating it was reconquered in 206 BC is imprecise.

Imperial examination — The claim that the examination system was the 'dominant path to high office' during the Tang dynasty is an overstatement; hereditary privilege and recommendation remained significant.

Imperial examination — The statement that the three-tiered ladder from local to provincial to court exams started with the Song dynasty is anachronistic; this structure was fully formalized in the Ming dynasty.

Jiangnan — The Liangzhu culture is dated circa 3300–2300 BC, not 2600–2000 BC.

Jiangnan — The entry incorrectly states that Chu defeated Yue as the primary event in Jiangnan; historically, Chu conquered Wu in the late Spring and Autumn period, and later conquered Yue in 334 BC.
