What did the movie "Seventy-seven Days" mainly talk about?

Seventy-seven Days is an adventure drama based on Yang Liusong's real experience and his novel The Wilderness of the North.

A paraplegic female photographer was paraplegic because of an accident, but she didn't sink in. Instead, I choose to continue my life and can only sit in a cold wheelchair to see the world and go where I want to go. Even more amazing, she also learned to drive, just like a model of being physically disabled and determined. In daily life, she smiles at life with perseverance, but actually complains about the injustice of fate.

An explorer who walked through Qiangtang no man's land met Lantian, a paraplegic female photographer, in Lhasa and was attracted by her bravery in the process of getting along with Lantian. In Yang's desperate situation, he was once in a trance, and his persistent smile under the blue sky was undoubtedly the driving force for him to persist all the way. After experiencing various crisis situations such as sandstorms, tornadoes and wildlife, we overcame difficulties with firm will and passion for polar exploration.

The film tells the story of the hero's 77-day adventure through Qiangtang no man's land.

Because Yang Liusong lost himself in life, he decided to venture into the snowy area alone and complete the adventure in the fantasy no man's land that the world could not complete. Before leaving, Yang saw the blue sky in Tibet. Blue sky is a stubborn and brave girl. She once fell down while filming the starry sky in Gangrinpoche, and her chest was injured, resulting in paraplegia. Although two-thirds of her limbs are unconscious, Blue Sky is still alive and optimistic. The attitude of living under the blue sky also inspired Yang. After 77 days, they stubbornly walked out of the no man's land.
