Vietnam under Chinese rule or Bắc thuộc (北屬, lit. "belonging to the north") (111 BC–939, 1407–1428) refers to four historical periods when several portions of modern-day Northern Vietnam was under the rule of various Chinese dynasties. Bắc thuộc in Vietnamese historiography is traditionally considered to have started in 111 BC, when the Han dynasty conquered Nanyue (Vietnamese "Nam Việt") and lasted until 939, when the Ngô dynasty was founded. A fourth, relatively brief, 20-year rule by the Ming dynasty during the 15th century is usually excluded by historians in their discussion of the main, almost continuous, period of Chinese rule from 111 BC to 939 AD.
The four periods of Chinese rule did not correspond to the modern borders of Vietnam, but were mainly limited to the area around the Red River Delta and adjacent areas. During the first three periods of Chinese rule, the pre-Sinitic indigenous culture was centered in the northern part of modern Vietnam, in the alluvial deltas of the Hong, Cả and Mã Rivers.
Elements of Chinese culture such as language, religion, art, and way of life constituted an important component of traditional Vietnamese culture until modernity.
Periods of Chinese rule
First Era of Northern Domination: 111 BC–AD 40
The first period of Bắc thuộc is traditionally considered to have started following the Western Han's victory in the Han–Nanyue War. It ended with the brief revolt of the Trưng sisters.
Second Era of Northern Domination: AD 43–544
Chinese rule was restored after the Trung sisters' rebellion. The second period of Chinese rule was ended by the revolt of Lý Bôn, who took advantage of the internal disorder of the waning Liang dynasty. Lý Bôn subsequently founded the Early Lý dynasty, with the official dynastic name "Vạn Xuân" (萬春).
Third Era of Northern Domination: AD 602–905
The Sui dynasty reincorporated Vietnam into China following the Sui–Early Lý War. This period saw the entrenchment of mandarin administration in Vietnam. The third period of Chinese rule concluded following the collapse of the Tang dynasty and the subsequent defeat of the Southern Han armada by Ngô Quyền at the Battle of Bạch Đằng. Ngô Quyền later proclaimed the Ngô dynasty.
Fourth Era of Northern Domination: AD 1407–1428
Vietnam was brought under the control of China following the Ming dynasty's defeat of the short-lived Hồ dynasty. The fourth period of Chinese rule ended when the Lam Sơn uprising led by Lê Lợi emerged successful. Lê Lợi then reestablished the Đại Việt kingdom (大越) under the new Lê dynasty.

I still don't really understand why antennas work![blob-no-thoughts blob-no-thoughts](https://www.hexbear.net/pictrs/image/1ef20b55-8fcc-4ed6-8fa2-57d4faa6b6a6.png)
Or what AC voltages people drive antennas with... can you get a shock if you touch one under certain conditions? Can an antenna short to something and pass dangerous current?
Yes and both are if they're struck by lightning.

Not only will radio antennas shock you (or the inanimate object you touch it with), the electricity arcs and sizzling will make the sounds of the frequency the antenna is broadcasting
Ohhhh fuck that's what people mean by RF burns![blob-no-thoughts blob-no-thoughts](https://www.hexbear.net/pictrs/image/1ef20b55-8fcc-4ed6-8fa2-57d4faa6b6a6.png)
Mechanism of RF burn is high-voltage arcing, still don't understand why it doesn't just pass through you and kill you tbh but now I know what to look up to find out
Thank you for the video
Edit: Soo I learned it's because the nervous system isn't affected by current at high frequencies, so it won't stop your heart. It can and will still burn you and cause damage by heating but probably no one can hold on to a source of RF current for long enough (very painful) for anything other than skin burning caused by high voltage arcing to your skin cuz unlike lower frequency current it won't force your muscles to contract and make you hold on
Something like that
