Why did Li Muzi finally take off his goggles and oxygen mask?

In the movie "She Disappeared", Li Muzi finally took off her goggles and oxygen mask, which symbolized her decision to free herself from power, bondage and freedom.

Throughout the film, Li Muzi has been in a controlled and restricted environment. As a miner, she was forced to do heavy work, wearing overalls, goggles and oxygen mask, and indulged in the depths of the mine every day. This bad working and living conditions made her gradually lose her self and freedom.

However, through a series of events and experiences, Li Muzi gradually woke up and realized his inner desire and real value. She realized that she was no longer willing to be controlled and bound by others, and she longed to have her own life and freedom again.

She was liberated from deprivation and bondage, and expressed her pursuit of freedom and her struggle against fate. This scene symbolizes her return to her true self, facing the world and embarking on her own journey again.
