غجا جوسون
Gija, a man from the period of the Shang dynasty, allegedly fled to the Korean peninsula in 1122 BC during the fall of the Shang to the Zhou dynasty and founded Gija Joseon. In the past, the earliest surviving Chinese record, "Records of the Three Kingdoms", recognized Gija Joseon. Gija's story was further developed in later Korean texts such as "Samguk yusa" and "Jewang ungi". By the middle of Goryeo dynasty, a state cult had developed around Gija. The "Dongsa Gangmok" of 1778 described Gija's activities and contributions in Gojoseon. The records of Gija refer to Eight Prohibitions (), that are recorded by the "Book of Han" and evidence a hierarchical society and legal protection of private property.
