Taejo of Goryeo
The Pyeongsan Shin lineage makes up about 70% of all those with the name Shin using the Chinese character 申. The clan's founder was General Shin Sung-gyeom. This clan associated with a mountain in North Korea called "Pyeongsan" (平山, literally "mountain of peace"). The mountain was originally named Samneungsan (三能山, literally "mountain of three talents"), without a family name, before being linked to the Shin surname by King Taejo of Goryeo.
