A long time ago, in a city in Persia, there lived two brothers, the elder brother was Cosimu and the younger brother was Alibaba. After their father died, in order to solve the problem of food and clothing, the two brothers had to work hard day and night.

Later, Cosimu was lucky enough to marry the daughter of a wealthy businessman. He inherited his father-in-law's property and began to embark on the road of doing business. Alibaba married the daughter of a poor family, and the couple lived a poor life.

One day, Alibaba drove three donkeys up the mountain to chop wood. Suddenly, a team of horses appeared in the distance, rushing towards this direction quickly. Alibaba was scared, so he had to climb up a big tree to hide.

The bandits tied their horses under the tree. At this time, a leader-like man carrying a heavy saddle bag came from the jungle to the big stone and murmured, "Sesame, open the door!" Then the robbers filed in. The leader walked last.

Alibaba stayed in the tree and watched them until they had disappeared without a trace, then he came down from the tree. He said to himself, "I will test the effect of this spell to see if I can open this cave door as well."

So he shouted loudly, "Open the door, Sesame!" As soon as he finished shouting, the cave door opened immediately. The cave was filled with treasures, which made people stunned. After Alibaba entered the cave, the cave door closed automatically again.

He had no worries and was not worried, because he had mastered the method of opening this door and was not afraid of not being able to get out of the cave. He was not interested in the treasure in the cave, he was in urgent need of money. Therefore, considering the carrying capacity of the donkey, he decided to just get a few bags of gold coins, tie them in firewood, throw them on the donkey and carry them away. In this way, people would not see the money bags and would still regard him as a woodcutter who made a living by cutting wood.

After thinking all this, Alibaba shouted loudly: "Open the door, sesame!" With the sound, the cave door opened, Alibaba took the gold coins he collected out of the cave, and then said: "Close the door, sesame!" The cave door closed in response.

Alibaba quickly returned to the city with the donkey carrying the money. After arriving home, he hurriedly unloaded the pack, untied the firewood bundle, and moved the bag of gold coins into the room and placed it in front of his wife. His wife told his brother that Alibaba got a lot of gold coins from somewhere.

Under the coercion of his brother, Alibaba had to tell him the location of the cave and the code words for opening and closing the cave door without missing a word. Cousimon listened carefully and kept all the details in mind.

Early the next morning, Cousimon drove the ten hired mules to the mountain. After everything was ready, he came to the closed cave door. But because he was too excited before, he forgot the codeword to open the door. In the middle of the night, the robbers came back from the robbery and cut Cassimus in half with a sword.

Alibaba also had a premonition of something unfortunate, but he calmed down and comforted his sister-in-law calmly: "Sister-in-law, Cassimus may be afraid that outsiders will know his whereabouts, so he took a detour back to the city, and he hasn't returned home yet. I think he will be back soon."

Alibaba recognized the bandits and knocked them out with drugs. While it was dark, they buried the bodies of the forty bandits without leaving any traces. Alibaba already had all the treasures in the cave, and he distributed the treasures to the poor so that everyone could live a good life.
