산은은
"산은은" is likely a typographical error or uncommon usage; if intending "산은," it means "Mountain is" or "As for the mountain" in Korean.
In this sentence, '산은은' uses the first '은' as a topic marker and the second '은' as an emphasis particle to highlight 'mountains'.
산은은 자연의 경이로움을 보여줍니다.
Mountains showcase the wonders of nature.
Here, '산은은' again uses both '은's to focus on the subject 'mountains' and emphasize their placement.
산은은 높은 곳에 위치해 있습니다.
Mountains are located in high places.
In this context, '산은은' emphasizes 'mountains' by employing reinforcement through repetition.
