During the Jiajing period of the Ming Dynasty, the country was settled in Beijing, and Nanjing was only the capital at that time.

Jiajing was the title of Zhu Houzong, the 11th emperor of Ming Dynasty (1September 507 16-15671October 23). Jiajing in Ming Dynasty took 45 years, which was the second longest title in Ming Dynasty (the longest was Ming Shenzong Wanli (the grandson of Emperor Jiajing), with a total of 44 years). Jiajing was the eleventh emperor of the Ming Dynasty. His father, Zhu Youjue, was not an emperor for a day, and was forced by Jiajing to chase after Ming Zongrui. His biological mother, Jiang, was made the Queen of Jiang. Jiajing's succession also means that filial piety was cut off in the Ming Dynasty.
