This episode tells the story of Ju Zhaxi Sang'e, known as the "Bird Lama", who embarked on a lifelong journey of ecological protection in the core area of Nianbaoyuze — starting from bird-watching in his childhood, moving on to painting birds, and then devoting himself to bird protection before stepping into ecological conservation.
It also depicts Wu Guojun, who takes the sky as his paper and balloons as his brush to write his commitment at an altitude of 30,000 meters, and has witnessed how plateau meteorologists have evolved from observing clouds with the naked eye to detecting weather with radar over nearly 30 years.
