The 트로이 목마, or Trojan Horse, is a famous story from Greek mythology that describes a clever ruse used by the Greeks during the Trojan War. After a long siege of the city of Troy, the Greeks built a large wooden horse and hid soldiers inside it. They left the horse at the gates of Troy and pretended to retreat, leading the Trojans to believe they had won. The Trojans brought the horse into their city as a trophy. That night, the hidden Greek soldiers emerged, opened the city gates for the rest of their army, and ultimately led to the fall of Troy. This tale symbolizes deception and the idea that appearances can be misleading.
