In 2025, we uncovered a WWII bullet in rural China. Just with a metal detector, it wasn't hard to find. Traces of war still lie scattered beside peaceful fields. Yet, a far more insidious legacy endures – chemical weapons once unleashed by the Japanese army, now embedded in human suffering. Locals call it "winter melon leg": relentless fevers, swollen limbs, days spent immobilized. The nightmare flares up every year, almost once a month. The war ended 80 years ago. The pain didn't. CGTN's feature The Main Eastern Battlefield: China in WWII commemorates the enduring memory of sacrifice and suffering.
