📖 Origin of the Hanja
The hanja "洪" combines 氵(water) + 共 (together) — waters joining into a great river. Korean Hong splits into Namyang Hong (descended from a Tang envoy) and Pungsan Hong (native). Hong Dae-yong (1731-1783) was a Bukhakpa scholar who argued for Earth's rotation centuries before it was widely accepted.
