In page Chewang Rinchen:

"

Chewang Rinchen was born in the village of Sumur in Nubra in 1931 in an illustrious family. One of his ancestors had the title of "Lion of Ladakh" for his bravery and his mother was known as "Mother of Nubra Valley" for her compassion.[1] Rinchen was educated in Sumur by a Ladakhi Christian missionary by name Stanzin.[1] At age 13, he attracted the attention of a kalon (duke) of Ladakh, who took him to Leh for secondary education. Four years later, the First Kashmir War started, placing Ladakh in grave jeopardy from the raiders from Gilgit-Baltistan.[2]
