"Iron Men," produced from discarded motorcycles, spare auto parts, gas tanks and scrap iron, stand several meters tall in the city of Zoucheng, Shandong Province, October 8, 2017. The creator of the metal works is retired technician Liu Konghua. Without any pre-planning, the talented retiree draws his artistic inspiration from the scrap he collects, transforming an abandoned exhaust pipe into the "Iron Men's" muscle and old vehicle wheels into the "Iron Men's" joints.
