The harsh natural environment makes maintaining Yubeng's electricity supply extremely difficult. During the 2020 Spring Festival, Wangden led his team into the mountain to repair the electricity supply equipment that had been damaged by continuous wind and snow. Because of the extreme weather, this mission left a lasting impression on him.

Yubeng's annual electricity consumption increased from 70,000 kWh in 2012 to 4,385,500 kWh in 2022 thanks to the construction of a 10-KV power grid. (Xinhua/Wang Guansen)
