Wongchu was born in Lower Solukhumbu, an area known for producing many Sherpa climbers. He spent his early years amidst the Towering Peaks herding the Yaks, all the while thinking about what it takes to climb those mountains. Obsessed with mountains, he left the village and started working in Climbing Expeditions as a porter and later advancing his role to Asst. climbing guide. In 2008 he finally started working as a Climbing Guide and since then he has successfully summited several peaks and led expeditions to various peaks.
