What is the official position of Wang Lang's "Situ"? What was its status at the time?

Wang Lang was a joke in "The Romance of the Three Kingdoms". He was scolded to death by Zhuge Liang, which made people laugh. It was simply the so-called absurd life and useless death. Of course, this is a literary work, so some characters will be darkened by the author. Wang Lang is actually very knowledgeable, and he is a master of Confucian classics together with his son Wang Su. When Cao Pi succeeded to the throne, he was appointed as the imperial censor and granted the title of Marquis of Anlingting. After the establishment of Cao Wei, Wang Lang was promoted to Sikong and granted the title of Marquis of Leping Township. After Cao Rui succeeded to the throne, Wang Lang replaced Hua Xin as Situ and was granted the title of Marquis of Lanling. He also ended up dying, not being scolded to death by Zhuge Liang as written in the novel. So what is the official position of Situ Wanglang, and what is his status?

1. Changes in Situ’s position. The position of Situ existed in ancient times, and later evolved from the three princes in the Qin Dynasty: the prime minister, the captain, and the imperial envoy to the three princes in the Han Dynasty. Specifically, the prime minister became the (big) Situ, and the captain became the (big) Sima. , Yu Da became (Da) Sikong, so Situ was ranked among the three Dukes in the late Han Dynasty and the Three Kingdoms period, but he had no real power and had high status and soft influence, which was the highest level of honor.

2. Wang Lang’s status. Wang Lang was promoted to Situ just one year before his death, so his highest official position was Situ. As mentioned above, the Situ position during the Three Kingdoms and Cao Wei periods was a false position, with high status and honor, but no real power. It was the highest position given by the country. Honor and recognition, so Wang Lang is a highly respected minister. However, there are still several official positions in Cao Wei that are slightly higher than Wang Lang's Situ. Cao Wei has the general, the Grand Sima, and the Taifu as the superiors. Their status is still higher than the three princes, so naturally they have a higher status than Wang Lang's Situ.

Although Wang Lang has no real power, Wang Lang still has a lot of say in Cao Wei. For example, Wang Lang once advised Cao Pi to go hunting often and not to return to the palace in the middle of the night. Cao Pi never returned to the palace in the middle of the night. Bad habits of the palace. Also during the Battle of Yiling, some people suggested that Cao Pi should raise troops to support the vassal Soochow and annihilate the Shu Han in one fell swoop. Wang Lang suggested that he should wait until the two armies were at a stalemate before leading troops to support, and send prudent generals to attack the Shu army. At the critical point, Wang Lang's opinions were taken seriously and adopted by Cao Pi, Emperor Wen of Wei.
