To fish in the troubled water(chinese pinyin: hun shui mo yu)，literally, it means catching fish in turbid water. Turbid water is not conducive to fish escape, so it is easier to catch fish in turbid water. Metaphor means to take advantage of the chaos for personal gain and profit. For example, to describe the chaos in the world, there is no monarch to manage the country in the turbulent times, and the uprising people take advantage of the chaos to plot for victory. Fishing in troubled waters also exists in Sun Bin's "art of war of Sun Tzu", which is the twentieth of the thirty-six.
