To earn more money, he became a construction supervisor for property developer China Evergrande Group. His salary was nearly 20,000 yuan per month. In 2018, he bought a car and took out a mortgage for a presold apartment. In 2019, he married his girlfriend.
In 2020, quitting his role at the property developer, Yin started his own business. In 2021, Yin and his family moved into their new home and now Yin plans to buy an apartment in a more suitable location for his son's education.
"From Yin's story, we can see how education and hard work has changed a man's life," the photographer Wu says.
