On March 4, the L8186 special train for migrant workers was ready to go at the WanYuan station. Zhao Wenhua, a farmer from the LuoWen township of WanYuan city, stuck his thumb out of the window and said emotionally to the railway staff on the platform: "It's so convenient to buy tickets and take the train here, thank you so much!"
WanYuan city is an old revolutionary base where the Fourth Front Army of the Red Army lived and fought for a long time. It is located in the northeast of Sichuan province, at the junction of the three provinces (cities) of Sichuan, Shaanxi, and Chongqing, and the intersection of seven counties and cities. It connects the economy and culture of Sichuan, Shaanxi, and Chongqing.
