Imagine being trapped for 30 hours, with no food, no phone, and no way out—except for a pillow and your own blood. This terrifying ordeal became a reality for a woman named Zhou in Sichuan province, China, who turned her desperate situation into a cry for help that would ultimately lead to her rescue.

The story began when Zhou was cleaning a guesthouse and accidentally locked herself in a bedroom. With the door's lock malfunctioning, she found herself alone on the sixth floor, completely cut off from the outside world. As time passed, panic set in. Without access to food or a bathroom, Zhou's situation quickly turned dire.

In a moment of sheer determination and desperation, she knew she had to act. Using her own blood, she wrote a plea for help on a pillow, inscribing the numbers '110 625'—the emergency service number and the room number she was trapped in. This shocking act highlighted the lengths to which one might go when faced with life-threatening circumstances.

Fortunately, her message caught the attention of a food delivery driver named Zhang Kun. He spotted the pillow tossed out of the window and immediately recognized the emergency number. Realizing someone was in distress, Zhang was quick to call the police.

In a dramatic turn of events, the police soon arrived to kick open the door, leading to Zhou's rescue. Video footage captures the moment when she thanked her rescuers, visibly shaken yet relieved. 'I went in there yesterday morning, and it’s been one day and one night,' she said, reflecting on the ordeal she had just endured.

Zhang Kun was celebrated for his quick thinking and awarded 3,000 yuan (about $540) for his role in her rescue, proving that sometimes, heroes wear caps and deliver food.
