The skilful tactician may be likened to the shuai-jan. Now the shuai-jan is a snake that is found in the Ch‘ang mountains.

In this quote, Sun Tzu draws an analogy between a skilled tactician and the snake known as the shuai-jan, which is found in the Ch‘ang mountains. This comparison illuminates the attributes that define a successful strategist—chiefly, cunning, adaptability, and the ability to capitalize on changing circumstances. The snake’s ability to maneuver through its environment with precision embodies the agility and cleverness required in tactical planning. The shuai-jan’s elusive nature suggests that a tactician must be both visible and invisible, striking when the moment is ripe while remaining hidden until the ideal time. This reflects the need for patience and an acute awareness of one's surroundings, allowing for effective responses to emerging challenges. Just as the snake uses its surroundings to its advantage, a skilled tactician must leverage the dynamics of their situation to outmaneuver adversaries. In modern contexts, these principles can be applied across various fields, including business, sports, and politics. For example, in business strategy, successful leaders must analyze market conditions, competitor behavior, and consumer trends, adjusting their approach swiftly to seize opportunities. Much like the tactician, they need to conceal their strategies while remaining prepared to strike decisively when the moment is favorable. In negotiations, adapting to the shifting moods and positions of the other party mirrors the adaptability of the shuai-jan. By staying observant and flexible, one can navigate complexities and secure advantageous outcomes. Overall, Sun Tzu’s metaphor serves as a timeless reminder that success in any competitive scenario demands not only preparation and skill but also the astuteness to adapt to ever-changing circumstances.
