A Chinese farmer, Zhang Shengwu, living near the Yangtze River in Anhui province, has built a working submarine with a surprisingly low investment of around $5,570.
Unlike common hobbies such as flying drones, collecting stamps, or building kit cars, Zhang spent a decade constructing his own submarine, which he calls "Big Black Fish".
Zhang, who grew up along the Yangtze River, has a background in shipping, farming, carpentry, and welding, but had no prior experience working on submarines.
He calls his submarine "Big Black Fish".
