Ruixian Fan and our director, Guo Qinhua, exchange a few words. Our on-screen participant is tired after and long night on duty. She sits in the onboard train office. The K165 from Xi'an to Kunming has been delayed several hours due to heavy rain and mudslides on the tracks. Before the next stop Ruixian Fan locks the bathroom doors. The train is moving very slowly. The train staff walk quickly through the carriages.
