Over the past seven years, Tsomo has received more than 50 postcards which are hung on the wall of her dormitory near the post office. "I feel warm every time I see them. They make me realize that my job is meaningful," said Tsomo.

The 8,848-meter high Mount Qomolangma presents dangers such as altitude sickness and bad weather. "The plateau bestows upon us a superior physicality, stronger lungs and heart, and a bright red face. These are gifts of nature," said Tsomo.

"Although my working conditions are hard, I will stick to my post and send blessings from Mount Qomolangma to more people across the world," said Tsomo.
