In history, why did Sima Yi conclude that Zhuge Liang was dying?

As the saying goes, if you are not afraid of eating too much, you are afraid of Pilate.

Lian Po was a famous soldier of Zhao during the Spring and Autumn Period and the Warring States Period. In his later years, he was excluded and went to Wei. Later, Zhao was besieged by Qin for many times and wanted to re-enable Lian Po. So the prince of Zhao sent messengers to visit Lian Po in Wei Liang, wondering if Lian Po was still alive.

Unexpectedly, Zhao's emissary was secretly bought by Lian Po's enemies, and poor Lian Po didn't know it. Facing the emissary, he ate a bucket of rice and ten catties of meat, and was also mounted on a horse to show off his working body. But when the messenger came back, he reported to the king of Zhao: Although General Lian is old and has a good appetite, he took a shit with me for a while and took it three times. ? The prince of Zhao thinks that Lian Po is old, and has never had the idea of reactivating Lian Po.

Xin Qiji, a bold poet in the Southern Song Dynasty, once expressed such feelings. Lian Po is too old to eat. . It can be seen that eating is a sign of good health to a certain extent. Hua deeply agrees with this view and resolutely implements it in practice. The first time I went to my mother-in-law's house, when I was having dinner, the scholar changed the habit of eating only one bowl of rice and ate two bowls of rice in a row. When my mother-in-law saw it, she was greatly satisfied, and the marriage was finalized.

The ancients believed that good health depends on whether you can eat or not. Although Sima Yi judged from Zhuge Liang's dinner that his life will soon come from the novel Romance of the Three Kingdoms, it is not accurate in the official history, but it also has certain scientific basis. In ancient times? Ten into a liter, ten into a barrel? Converted into rice in the present way is about 1.25 kg per liter and 12.5 kg per barrel.

Veteran Lian Po, as a military commander, can eat a bucket of rice and ten catties of meat at a meal. Let's just say that the standard of ancient people's physical strength is that they can eat a bucket of rice at a meal. Therefore, when Sima Yi learned that Zhuge Liang's daily appetite was only a few liters, he thought that Zhuge Liang's diet could not keep up, plus a lot of mental work every day (forgetting to eat and sleep), so he concluded that Zhuge Liang would be dragged down sooner or later.
