Professor Wei Kang was most worried about how unfamiliar they were with Egyptian culture and living conditions. Although he would definitely hire a guide after arriving there, the guide was only a guide in geography. It would be too extravagant to expect them to know the culture and language of ancient Egypt. He probably could not afford a guide who had such knowledge.
When it came to Chinese history, it must be said to be 5000 years in length, and when it came to Egyptian history, it must be said to be 7000 years. But in fact, the history of ancient Egypt was actually only 5000 years long. When the era of Cleopatra ended, it was completely interrupted. The latter 2000 years were no longer the era of pharaohs. The inheritors threw the culture and heritage of ancient Egypt into the rubbish heap of history, and the Arabs replaced the real Egyptians to become the masters of that land.
