Sun Tzu said: The art of war is of vital importance to the State. It is a matter of life and death, a road either to safety or to ruin. Hence it is a subject of inquiry which can on no account be neglected. Therefore, the classics are based on five (things), and the schools are based on their plans, and their feelings are asked: one is Tao, the other is heaven, the third is earth, the fourth is generals, and the fifth is law. The Tao makes the people and the people agree, so they can (to) die with it, and they can (to) live with it, instead of (fear of danger) (paradox). Heaven signifies night and day, cold and heat, times and seasons. Earth comprises distances, great and small; danger and security; open ground and narrow passes; the chances of life and death. The Commander stands for the virtues of wisdom, sincerely, benevolence, courage and strictness. Dharma, music system, official way, the main use also. All these five will be heard, those who know will win, and those who do not know will be defeated.

Attention should be paid to the fact that it is best not to have farmland water flowing into the ponds around, because pesticides must be applied to grow rice now, and if pesticides flow into your ponds, your shrimps will die a lot. If they die, they will generally sink to the bottom of the water, and you cannot find them. Therefore, attention should be paid to the selection and pulling. Water sources should be guaranteed and water should be exchanged for drainage and irrigation.
