In the 23rd year of Chenghua, Queen Zhang became the Crown Princess, and Ming Xianzong died in the same year. The only son of Ming Xiaozong naturally succeeded to the throne and became Ming Xiaozong. Isn't the mountains and rivers of the Ming Dynasty very good after Emperor Xiaozong ascended the throne? Beautiful? After the efforts of Emperor Xiaozong of Ming Dynasty, the Ming Dynasty got some recovery, so when Emperor Xiaozong was in power, he spent all his time governing the country. Where does he have time in the harem? In addition, Ming Xiaozong still likes the lively Queen Zhang, so Ming Xiaozong has never expanded the harem.
In addition to Ming Xiaozong's lack of time, he also likes Queen Zhang, and Ming Xiaozong doesn't want his harem to be like Ming Xianzong. During Ming Xianzong's time, Wan Guifei was a special pet, but in order to prevent other concubines from receiving preferential treatment, she aborted the children of those pregnant concubines, resulting in Ming Xianzong having no children. Ming Xiaozong can be hidden in Wan Guifei by the imperial palace, so his childhood is not easy, which is why Ming Xiaozong hates the harem and doesn't want to be included in other concubines.
It is really hard for Ming Xiaozong to insist on only one wife, Queen Zhang. After all, it is common for ancient men to have three wives and six concubines. If not, I'm afraid they will be urged by their elders to get married more so that they can flourish. However, it is precisely because Ming Xiaozong insisted on not accepting other concubines that their love story was also achieved.
