A woman named Chen from Hunan, China, got trapped in her company's freezer. She was moving goods alone and accidentally locked herself inside. The temperature was very cold, at minus 20 degrees Celsius, and she had no phone. Chen tried to make noise by banging a box and her slipper on the door. Luckily, a delivery rider named Liu Xu heard her and helped her get out. She was very cold and took two hours to feel better.

To thank Liu, Chen gave him flowers, food, money, and even offered him a share in her company. Chen said, "I would definitely have frozen to death if no one had heard me." She also promised to fix the freezer and reminded everyone to follow safety rules.
