Is “What are the similarities and differences in Wu Zetian's initial entry into the palace?” true?

The official history records her entry into the palace and her deposition. The Old Book of Tang, Annals of Empress Wu Zetian, records: 'Emperor Taizong heard of her beautiful appearance and summoned her to the palace, establishing her as a talented person.' The novel Romance of the Sui and Tang Dynasties, chapter 70, dramatizes her gaining favor and the rumor of a secret record: 'At that time, Venus appeared frequently in the daytime, and the Grand Astrologer divined that a woman would become sovereign. The people also spread a secret record saying: "After three generations of Tang, the female sovereign Wu will rule the world."'
