Another Qingming Festival is approaching. Yang Jie (played by Huo Siyan), a beautiful girl who grew up in an orphanage and has a domineering personality, received a letter saying that they had not seen each other for a long time and invited her to come back for a visit. A train ticket to "Qingming Station" was attached to the letter. Yang Jie returned to the orphanage, but found that the sender was not the dean who took care of her that year. In order to find out the truth, she decided to board the mysterious train. The train was strange and gloomy, and the atmosphere was solemn. The train conductor (played by Wang Shuangbao) had an unpredictable expression and seemed to have a hidden secret. The crazy woman (played by Hui Yinghong) who cooked in the dining car recognized Yang Jie as her daughter and was greatly frightened. Fortunately, she met the handsome and handsome Red Hair (played by Li Zonghan) on the way. Give her a brief and illusory comfort. What needs to be faced will eventually be faced. That forgotten experience is slowly revealed on the way to Qingming...
