Xiao Zhang works in a factory, and his workshop director is a greedy and mean guy. Not only does he often deduct workers' bonuses in various ways, but he also forces his colleagues to invite him to dinner. Therefore, everyone hates the director.

Everyone in the factory lived in the staff dormitory. Xiao Zhang and his co-workers lived in the dormitory building at the back, while the director lived in a small bungalow at the front.

One night, Xiao Zhang returned to the dormitory after working the night shift. When he passed by the director's bungalow, he suddenly found a few cannons in his pocket, which had been left over from playing with his son during the holiday.

Thinking of the director's nasty face, Xiao Zhang suddenly had the idea of a prank. Seeing that there was no one around, he quietly took out two cannons, slammed them hard against the director's window, and then ran away.

The next day, seeing the director's red eyes and yawning, Xiao Zhang was overjoyed.

From then on, every time the director deducted the bonuses of the co-workers or forced them to treat, as long as it was Xiao Zhang's turn to work overtime, he would throw two cannons at the director's window. The next day, Xiao Zhang saw the director's sleepy and angry appearance, and his heart was more balanced.

On this day, it was Xiao Zhang's turn to work overtime again, because he had just been blackmailed by the director for a good cigarette two days ago, so this time Xiao Zhang was going to throw a few more cannons for revenge. Unexpectedly, he just took out the cannon, but before he threw it away, a fat security guard suddenly appeared and caught him on the spot. Because they were all employees of the same factory and knew each other, Xiao Zhang begged the fat security guard for mercy, asking him to let him go and promised never to throw it away again.

The fat security guard pulled Xiao Zhang aside expressionlessly and whispered angrily, "No, you have to throw it a few more times!"

Xiao Zhang was stunned when he heard that. He didn't know what kind of medicine he was selling in the gourd. Then the fat security guard whispered to Xiao Zhang, and Xiao Zhang understood what was going on.

It turned out that there were two security guards on duty in this dormitory, and Xiao Zhang and the others also took turns working overtime, and the shift of the fat security guard and Xiao Zhang happened to be the same. Every time Xiao Zhang's director complained to the fat security guard's leader, the fat security guard's leader would scold the fat security guard, saying that he must sleep on the night shift, otherwise why would others be fine when they were on duty? So the fat security guard wanted Xiao Zhang to stagger his duty time and throw it a few more times, so that their leader would change his opinion.

Xiao Zhang immediately agreed, but if he wanted to change the time, it would not be his turn to work overtime, so he had to climb out of the quilt in the middle of the night to throw cannons, which was very inconvenient. At this time, the factory had just arranged for Xiao Zhang to go on a business trip out of town, so Xiao Zhang thought of Xiao Wang, the most close-knit worker. The two of them worked overtime at staggered hours, so it was just right for Xiao Wang to do this.

Xiao Zhang told Xiao Wang about this, and Xiao Wang immediately agreed.

A few days later, Xiao Zhang came back from other places, and as soon as he came back, he immediately went to Xiao Wang to ask how it was going. Unexpectedly, as soon as Xiao Wang saw Xiao Zhang, he hurriedly pulled him aside and happily said, "Fortunately, you are on a business trip, otherwise this time it will be troublesome!"

Hearing that, Xiao Zhang hurriedly asked, "What happened?"

Xiao Wang smiled bitterly and told him, "That fat security guard is so unlucky! Because a few days ago, their leader said that he was sleeping on duty and he was not convinced, so their leader transferred the shifts of the two security guards to see if he was wronged."

Xiao Zhang was stunned, and after a long time, he asked worriedly, "What should I do if I transfer the fat security guard?"

Xiao Wang said sympathetically, "The fat security guard rushed to the workshop to find you when he saw that you were on a business trip, but when he heard that you were on a business trip, he thought it was fine. But I didn't know about it, I threw three guns that night, and the fat security guard was so angry that he confessed you. Unexpectedly, when their leader found out that you were on a business trip outside, he was suddenly furious, saying that not only was he not serious about his work, but he slept on duty, and his character was not good, so he framed someone, so he fired him directly!"
