Liu Huanrong works in Changqing oil fields, China's second-largest onshore oil and gas field located in Inner Mongolia. A devoted employee for over thirty years, he spends his free time building a swing and running after his young female coworker, who recently arrived and has only one thing in mind: fleeing the isolated place to return working in the big city. An unexpected mishap brings Liu back to his family in Xi’An, the 8 million inhabitants capital of Shaanxi Province. He will have a tough time reconnecting with his estranged spouse and adult daughter, but also with a very different capitalist society compared to thirty years earlier.
