Insider - Understanding内鬼-认知

深居简出躲深处 销声匿迹善隐藏 深入虎穴不畏险 孤军奋战获情报 忍辱负重待时机 里应外合不露面 神出鬼没无行踪 内鬼通常是间谍 Living secluded and hidden, disappearing without a trace, adept at concealment, venturing into the lion's den without fear, fighting alone to gather intelligence, enduring hardship and waiting for the right opportunity, working from within and without revealing themselves, appearing and disappearing without a trace. An insider is usually a spy.
