"People sit at home, and the top scholar reaches the sky". What was the "metaphysical event" in the Ming Dynasty?

The "metaphysical event" in the imperial examination center, in which "people sit at home and the top scholar falls from the sky", refers to the fact that the top scholar in the imperial examination system comes not by the actual achievements of the imperial examination, but by some mysterious things, such as being handsome. History books record many "mysterious events". Here are four mysterious events: "When people sit at home, the number one scholar falls from the sky".

The first thing is that the first place was demoted because of ugliness, and the second place was promoted to the first place because of its handsome appearance. In the second year of his reign, Wang Gen won the first place in the palace examination, and everyone was not as good as Wang Gen, but Wang Gen was too ugly, while Hu Guang, the second place, was relatively handsome. He boldly rebuked the captaincy and won the emperor's heart. Because of her high face value, she rose to the first place, while Wang Gen fell to the second place because of her ugly appearance.

The second mysterious thing is that he was demoted because he was from the same town as the examiner, and he was demoted because of his uncommon name. Subsequently, the third place inexplicably became the champion. In the 13th year of Yongle, Chen Xun took the first place in the exam, but he and the two examiners on the spot were fellow villagers. In order to avoid suspicion, he left the first place in Chen Xun. The second place Lin was pushed up, but the examiner found that the word "straw" in Lin's name was too difficult to recognize, so Lin was also pushed down, and finally the third place Hong Ying was listed as the first place.

The third thing is that the emperor was moved by this name and he was promoted. Ming Daizong Jingtai five years, this year's palace entrance examination was attended by Emperor Jingtai himself. When he saw Sun Xian's name, he couldn't help mumbling. However, the emperor's mumbling was heard by the examiners. They suspected that the emperor was partial to Sun Xian, so they appointed him as the top scholar. So the Sun Xian examinee inexplicably won the first prize because of his name.
