Zhang Canjiao's curse in history?

In Romance of the Three Kingdoms, opening angle is a magical skill that can call the wind and rain and scatter beans into soldiers. This must be the myth of Zhang Jiao, the author of romance novels. How can mortals know magic, and how can they die after learning the opening angle of magic? It is certainly untenable to say that the disease will not heal itself. Magic is not a medical skill, and it definitely does not belong to people. How could he die? So what is certain is that the opening angle can't spell.

Then the problem is coming. Since Zhang Jiao can't spell, what are those seemingly magical things? Let's analyze it for everyone.

Say yes, the opening angle can do magic. What is magic? Magic is to use some special props to convey a mysterious illusion and confuse others according to scientific principles in order to achieve the effect of confusing the real with the fake. In the era when feudal superstitions prevailed in the Three Kingdoms and the Eastern Han Dynasty, some tricks might make people believe that Zhang Jiao really knew magic. According to the present statement, Zhang Jiao is an expert in social psychology, mathematics, chemistry, physics and performance.

Second, the opening angle is to observe the night sky at the right time and place, which shows that the opening angle is familiar with astronomy, geography and meteorology. It's like setting up an altar in Battle of Red Cliffs's Zhu Gekongming, saying that you want to borrow the east wind. This is actually just Zhuge Liang's prediction of when there will be an easterly wind with his rich meteorological knowledge, so all the knowledge on the altar is put on airs and not true. Only in romance, Zhang Jiao predicted when it would be windy and when it would rain, and then took advantage of the situation at a specific moment, giving people the illusion that Zhang Jiao was casting spells, so it was just ignorance of the world.
