One etymological hypothesis suggests that the name Seorabeol might have been the origin of the word Seoul, meaning "capital city", and also the name of the present capital of South Korea, which was previously known as Hansung (漢城) or Hanyang (漢陽).
En etymologisk hypotese (der er forskellige andre spekulationer) antyder, at navnet Seorabeol kunne have været oprindelsen af ​​ordet Seoul, der betyder "hovedstad", og også navnet på den nuværende hovedstad i Sydkorea, en by tidligere kendt som Hanseong (漢城) eller Hanyang (漢陽).
