High-speed trains, tunnels and bridges, all in the backyard! During the pandemic, Zhang Yadong, a college student who lives in Henan, China, built this miniature infrastructure in his grandma's vegetable garden. Segments of the structural project were designed and crafted in a room-turned-lab in his house. He even looked for methods by watching railway construction documentaries. After three months of work, his little world was finally completed.
