First, Li Bai's position is inferior to that of the prime minister. Although Li Bai's status is very high now, it is because Li Bai's poetry is a beautiful sentence that has been sung through the ages. But in the Tang Dynasty, although Li Bai was famous, he was also appreciated by the royal family. However, compared with the position of prime minister, it is still relatively low. The prime minister holds great power, is the emperor's reliance on political affairs, and is also the first of 100 officials. So Li Bai's position is not as good as that of the prime minister. Moreover, for his own career, Li Bai agreed to adopt his wife's family by adoption, and with the help of her husband's family background, he was blessed in his career. The husband's family is the prime minister's family and is admired by more people.
Second, the customs and opening-up in the Tang Dynasty have always been superior to women in the traditional history of China. Therefore, no matter how big the gap between men and women's family status is, girls should marry into boys' homes. However, the Tang Dynasty was different. The atmosphere of the Tang Dynasty was very open, and the status of women was greatly improved. Women can choose their own clothes or become officials, and even the only female emperor appeared in China history. It is normal for Li Bai to be adopted by her husband's family. However, Li Bai's wife was born in a prime minister's family and a well-known family. Therefore, it is reasonable for Li Bai to accept his son-in-law.
Although Li Bai is a famous poet in the history of China, his position in literature is very high. However, in the Tang dynasty, compared with Li Bai's wife who was born in the prime minister's office, her wife had a higher status. Because his wife's father was the former prime minister of the imperial court, Li Bai chose to take his son-in-law into his wife's family in order to better develop his career.
