She wants to escape from the prison
Zhang Yun's life is like a pool of stagnant water. Her husband is inconsiderate and cowardly towards her, her mother-in-law is critical all day long, and the life in the countryside is so depressing that she can't breathe. She had had enough and decided she couldn't take it anymore.
So, she began to secretly save money, never letting go of a penny, with only one thought in her mind: escape! Run away far away and start over in a big city.
Finally, she took the money she had saved and boarded the train to the big city without looking back. Life in the big city isn't easy, but at least she has freedom. She studied while working, and slowly gained a foothold.
Although she had abandoned her husband and son, her life was much better than in the countryside. In the dead of night, Zhang Yun still missed her son very much.
After witnessing the prosperity of big cities, where will she go? Should she escape from the prison that restrains her or continue to live an ordinary life?
