Borrowing an arrow from a straw boat is a very famous allusion in Chinese history, and it is also a very scheming means in The Romance of the Three Kingdoms. At that time, Zhuge Liang drove three wooden boats, surrounded by scarecrows, and then sailed to Cao Cao's camp. At that time, Cao Cao thought that the enemy was coming, so he ordered to attack with wooden arrows. These wooden boats, of course, are arrows shot at the scarecrow, and of course they are left on the scarecrow.

Then someone asked, if Cao Cao had used rockets, Zhuge Liang would have been wiped out. At that time, the production process was particularly troublesome for rockets, because some grass and animal fat were tied to the rockets. At that time, the production of animal fat was particularly troublesome, because the technology was relatively backward and the process extraction was particularly troublesome. So because the soldiers were in a hurry, they shot with wooden arrows. I didn't expect to use rockets, and it was only used with the development of production technology, but that was already in the Tang Dynasty. At that time, because the tools were simple and the technology was underground, it would be more expensive to use rockets. I didn't expect so many things at that time, so I didn't use rockets.

Then Zhuge Liang was also very clever. Unexpectedly, he also thought of Cao Cao's practice, so the plan succeeded. If he had used a rocket, Zhuge Liang would not have survived, so Zhuge Liang would not have appeared in the later process. Of course, this is definitely impossible. This may just be an allusion in the Romance of the Three Kingdoms, and its authenticity needs to be verified.
