Green is dead, 16 years old, on the Zoige grassland. The news was broken by Yifeng, with a single sentence: "It has finally turned into the wind and returned to the grassland," and the whole internet followed with tears. When I scrolled to the video, my phone paused on the cover of the 2013 documentary, where the little wolf cub peeked out from Li Weiyi's arms, and in the blink of an eye, it became a legend. Later, it truly rejoined the wolf pack, wearing a collar and running in the snow, with only its back visible in the footage. After that, the signal was lost, everyone knew it in their hearts, but no one dared to say it. Now that it's finally confirmed, there's a sense of relief. Sixteen years, longer than most dogs, if a wild wolf can live like this, it's a huge win. It didn't come to this world in vain. It taught us reverence, and also taught us to let go.
