The Chinese heard that Westerners promoted the Egyptian pyramids and recorded them in the book in 1839, when Lin Zexu presided over the smoking ban in Guangzhou, in order to understand the history and current situation of Western countries, Lin Zexu asked his staff to translate the "World Geography Encyclopedia" written by the British Murray in 1836, and personally polished and edited it, and finally wrote the "Four Continents".
And ancient Egypt is recorded in the "Chronicles of the Four Continents"."Many countries"In the book, it is written that there are seven wonders in the world, and there are two countries in many countries, which are built by King Duolumao, and the pointed platform and the high platform of Faro Island, but there is no nonsense since ancient times, and there are no relics to collect, Lin Zexu is skeptical.
From the book, I learned that the pyramid was a pointed platform, and the way of construction was to build it against the mountain and make of fine white stone. The main component of fine white stone is calcium carbonate (caco), the most intuitive common item, that is, lime soaked in water and mud and sand, before the popularization of modern cement, it was commonly used to build red brick houses in rural China.
It is very different from the granite boulders advertised in today's textbooks, and the pyramids that the blade can't fit into
In other words, when the Englishman Muri wrote the "World Geography" in 1836, the pyramid was still built of fine white stone, and then rebuilt with huge stones?
But in 1777 the French traveler and diplomat Benoit de Mailet wrote the Description de L'égypte）。In this book, Benoît de Mayer describes the interior of the pyramid and mentions that the stones of the pyramid are so closely connected that it is difficult for even a blade to insert it, and that the pyramid was discovered earlier than Napoleon in 1798.
In short, the Europa people have different accounts, in the end, are the French telling the truth or the British? I don't know, but someone must be making **.
After all, the textbook says that the pyramid is built of a boulder and the blade cannot be inserted, so believe the French for the time being!
However, there are different opinions in the scientific community, such as CNKI.
It is mentioned that the megaliths of the pyramids are made of concrete, and they are the result of joint research between the French and the Americans. It is the same point of view as the record of Lin Zexu's "Chronicles of the Four Continents" in 1839.
More information. 
Well, no matter what Westerners say and how their views change, the author still believes that in 1839, Lin Zexu recorded in "Sizhizhou" that the high platform was built on the mountain and made of fine white stones.
