After Zhuge Liang's death, what is the use of asking for seven grains of rice in his mouth?

We all know that in ancient times, science and technology were not as advanced as they are now, and there was no weather forecast in ancient times. In TV plays, we also saw that the imperial court also set up officials to observe the stars. They all predicted the weather and the development of Jiangshan. Therefore, the ancients had a lot of research on astrology and developed a set of theories. The stars in the sky of the ancient people all correspond to the people on the ground. For example, purple and purple stars are noble imperial stars in the eyes of the ancient people and are implicated in the fate of the emperor.

With the lessons of Pang Tong, Zhuge Liang paid more attention to the study of astrology, and the Seven-Star Lamp was one of the research achievements. But besides the Seven-Star Lamp, he also had a stunt in the closet, that is, continuing to be a star. When a person's body dies, his spirit will die, and the star in the sky is a reflection of his spirit. If Zhuge Liang dies, the star that represents him will also go out. Sima Yi just knows a little about astrology. If he finds that Zhuge Liang has put out his star, he will definitely lead an army to fight back. Therefore, Zhuge Liang has seven meters in his mouth, just to let his star continue for a long time with these seven meters. This is also called feeding the star rice.

We often say that Zhuge Liang knows astronomy above and geography below, and his study of astronomical phenomena is naturally deep. He and his opponent Sima Yi often watch the stars at night to predict the fate of both sides. During the Northern Expedition, Zhuge Liang found that his time was coming, and Sima Yi naturally found out, so he has been waiting for Zhuge Liang's death. In ancient times, people often had jade in their mouths after death, but why did Zhuge Liang let rice go? Because this is related to the funeral etiquette in ancient times, the rule at that time was that the scholar-bureaucrat died with rice in his mouth, so it was also in line with the rules that Zhuge Liang died with rice in his mouth.

Zhuge Liang tried to fight for his life through a bright lamp array, but Wei Yan inadvertently destroyed the array, which was finally irreparable. Although Zhuge Liang was helpless, he knew that it was God's will, and he was unable to resist, so he had to take the time to arrange his own affairs. At that time, the Shu army was still fighting against Wei Jun. In order not to disturb the morale of the army, he asked Yang Yi to temporarily conceal the news of his death, put himself in a big cabinet, put himself in a sitting position, and then put seven grains of rice in his mouth and another lamp at his feet. As for why is it seven? Because there is an ancient saying that the soul will come back once after seven days of death, which is also called the first seven, so containing seven grains of rice can keep his general star from falling for a while and make the enemy think that he is not dead.
