As follows:
Four people carrying the coffin is the simplest way of burial. It also reflects that Zhuge Liang did not pursue fame, wealth and ostentation throughout his life. During the war, four people carried the coffin. The coffin is also relatively hidden, so his whereabouts will not be exposed. The burial with the rope broken also adds to the mystery of Zhuge Liang's tomb. No one knows where he is buried.
Similarly, why did Zhuge Liang go south? In fact, there is also a saying that among the five elements, the south belongs to fire, and Zhuge Liang's own life belongs to earth. Being buried in the south is a sign that fire creates earth.
The four people carried the coffin south, and the rope was broken and buried. What’s the meaning?
Zhuge Liang paid attention to simplicity throughout his life, and he was equally frugal after his death. He had a high status under the emperor in the country, but he was not luxurious. He just let four people carry his coffin all the way south.
These four people were also his close friends during his lifetime. They kept walking south until the rope broke, which was also when he was buried. The burial place was where the rope broke. Many people were right. This matter is unclear, but based on the superficial knowledge in historical documents, it is likely to be related to Feng Shui.
