Trưng Trắc (Zheng Ce)'s husband was Thi Sách (Shi Suo), was also the Lac lord of Chu Diên (modern-day Khoái Châu District, Hưng Yên Province).
[18][verification needed] Other sources indicate that Trưng Trắc's movement towards rebellion was influenced by the loss of land intended for her inheritance due to the replacement of traditional matrilineal customs.
The strategic importance of Jiaozhi is underscored by the fact that the Han sent their most trusted generals, Ma Yuan and Duan Zhi to suppress the rebellion.
[7] In the spring of 42 CE, the imperial army reached high ground at Lãng Bạc, in the Tiên Du mountains of what is now Bắc Ninh.
Yuan pursued Trưng Trắc and her retainers to Jinxi Tản Viên, where her ancestral estates were located; and defeated them several times.
[28] Trưng Trắc's husband, Thi Sách, first escaped to Mê Linh, then onward to a place called Jinxijiu and was not captured until three years later.
"[27] In their reconquest of Jiaozhi and Jiuzhen, Han forces also appear to have massacred most of the Lạc Việt aristocracy, beheading five to ten thousand people and deporting several hundred families to China.
[30] General Ma Yuan aggressively sinicized the culture and customs of the local people, removing their tribal ways, so they could be more easily governed by Han China.
He melted down the Lac bronze drums, their chieftains' symbol of authority, to cast a statue of a horse, which he presented to Emperor Guangwu when he returned to Luoyang in autumn, 44 CE.
[37] The successful reconquest of Northern Vietnam also gave the Han dynasty secured gateways to access southern maritime trade routes and establish ties with various polities in Southeast Asia and beyond, and increasing relationships between China and the Indian Ocean world.
[39] Along with trade and knowledge, religions such as Buddhism possibly spread to China via Northern Vietnam from southern sea, along with obvious inland Silk Road, during the second and third centuries.
Lǐ (俚) and Lǎo (獠) are interchangeably perceived as non-Chinese and contemporary sources did not prefer a specific ethnicity for them, the culture could have been multiethnic as modern Vietnam and Southern China are, made up by primary Kra-Dai and Austroasiatic speaking tribes,[42][43] but some probably were ancestors of modern-day Li people in Hainan.
Meanwhile numerous independent Dong chiefdoms representing the Li Lao drum culture's autonomy created the voidness of imperial authorities in the regions that were inside the empire.
[45] According to researcher Catherine Churchman in her 2016 book The People Between the Rivers: The Rise and Fall of a Bronze Drum Culture, 200–750 CE, due to Li-Lao culture's massive dominantly influences, instead of becoming more assimilated into China, the Red River Delta from 200 to 750 CE experienced a reverse effect on sinicization or "de-Sinifying effect", therefore the history of sinicization of the region should be reconsidered.
Modern Vietnamese historians and social activists however retroactively ridiculed and mocked men for doing nothing while "mere girls", whom they viewed with revulsion, took up the banner of revolt.
