"Sound east strikes west" literally means that if the planner wants to succeed in the west, he deliberately poses a posture to attack in the east and deliberately confuses the enemy. In fact, the essential meaning is the same as the literal meaning. Sound east attack west is deliberately in the east to make a noise, how big the movement is not important, the key is to make the other party believe that you are indeed moving in the east, so as to relax the defense in other directions; or to disturb the other side's judgment, not sure which place is the direction you want to attack, so that everywhere to fortify, it is equivalent to not defending everywhere. In short, it is to be deceived by the other side, if not deceived, the combo should not be hit, in vain to increase casualties.

The learning of this plan lies in how to make a sound, but also to confuse the other party and create favorable opportunities for themselves. Arranging who to "sound east" is indeed an artistic job, and no good actor really can't act well.
In 1944, the United States and Britain allies planned to land in western Europe to open a second battlefield, and there were several alternative locations, and the discussion was discussed, leaving only normandy and Calais, two beaches. Eventually, the Allies set the landing site for Normandy. In order to attract the German army to strengthen the defense of Calais, the Allies also played a trick of attacking the east and the west, creating a atmosphere of landing in Calais, and even set up a Calais landing command, the commander of which was the famous American four-star general General Patton. The Germans mistakenly believed that the Allies were going to land in Calais, thus relieving the defenses in Normandy. By the time of the scheduled attack on June 6, 1944, when the main Allied forces had attacked from Normandy, it was suddenly realized that the real landing site was Normandy and not Calais, but it was too late.

The strategy of attacking the west is very simple, and it is also very simple to crack this plan, and it is easy to calculate the plan and use the other way to return to the other body. This trick was very effective, and even Cao Cao, a generation of tyrants who had annotated the Art of War of Sun Tzu, also planted a heel.
In 198 AD (the third year of Jian'an), Cao Cao led an army to attack Zhang Xiu in Nanyang, and Zhang Xiu lost a while with a single force, so he was so frightened that he hung up the battle card and hid in the city. Cao Cao circled around Nanyang City and found that the southeast corner of the city was the weakest, intending to use this as a breakthrough. Therefore, he arranged for some military horses to make a big noise in the northwest corner of the city, giving people a posture of attacking the city from the northwest corner. Secretly, he had most of the horses prepare siege equipment in the southeast corner of the city. Cao Cao's plan to attack the east and the west was discovered by Zhang Xiu's adviser Jia Xu, who suggested that Zhang Xiu return the favor in the other way. Let the people of the city put on the clothes and armor of the soldiers and garrison in the northwest corner of the city, make a tit-for-tat appearance, and at the same time hide the elite troops in the southeast corner of the city, waiting for the opportunity to resist the enemy. After Cao Cao was ready to stop, he led his troops to attack the city from the northwest corner during the day, and at night, he let the elite soldiers attack the city from the southeast corner of the city. When the Cao army climbed to the head of the city, Zhang Xiu's ambush troops rushed out from all directions and repelled the Cao army's attack.
Jia Xu
In this battle, Cao Cao attacked Zhang Xiu with the strategy of attacking the west with the sound of the east, but was caught off guard by Zhang Xiu's strategy of attacking the west with the sound of the east. The main reason for cao Cao's failure in this plan was that Zhang Xiu did not take his lead and knew that his main attack direction was in the southeast corner rather than the northwest corner, so he made full preparations for the enemy in the southeast corner.
The eighth plan of the Thirty-Six Counts, "Dark Crossing Chen Cang", is somewhat similar to "Sound East Strikes West", and both use blindfold methods to confuse the enemy. However, the details are also slightly different. "Sounding east and striking west" is a big fanfare in the east, lest the people of the world not know that he is going to do it in the east; while "secretly crossing Chen Cang" is to let people see that he is repairing the boardwalk, but does not publicize it, only does not say it. One is to both say and do, and the other is to just do and not to say. Regarding the strategy of "secretly crossing Chen Cang", there will be a separate interpretation and will not be expanded here.
