Here are a very old Korean mother and her son. They have lived together for over 45 years without a husband and father. 44 years after he died, they embarked on their first journey in 2014, when they headed for an old Buddhist monastery on the Himalayas. Then they had a pilgrimage for Mustang, the Buddhist kingdom and Myanmar. Finally, in 2017, when the mother got 83 years old, they embarked on their last journey for the sacred mountain, Kailash.
