Hunan's last slow train. Without this car, we will be poor for a lifetime.

Sometimes, slowness is also a feeling. When the high-speed rail era roars and the distance between cities gets closer and closer, in Huaihua, Hunan, there are still four green "slow trains" that have no air conditioning, no soft seats and soft sleepers, and stop at the station. Walking through the depths of the mountains, slowing down the vegetable farmers, fruit farmers, residents, railway workers and students along the line, they are memories of an era.
