Empresses in Tang dynasty:

The Tang Dynasty was in a period of great ethnic integration, deeply influenced by Hu customs, and the social atmosphere was relatively open, and the shackles of Confucian traditional thoughts and female concepts on women were greatly weakened. Therefore, the Tang dynasty did not guard against the interference of the concubines in politics, and the concubines in the Tang dynasty had a strong desire to participate in politics in a more direct way. The cruelty of political struggle will inevitably make many concubines in the Tang Dynasty pay the price of being abolished and killed.

The main reason why the concubines in the Tang Dynasty were abolished and killed was not that they were old and childless, but that they participated in political struggles. Empresses and concubines in the deep palace are actively or passively involved in political struggles for their own and family's vital interests. Winners enjoy wealth, losers live in limbo, or lose their hair or even die. There are also queens who did not participate in political activities, but became innocent victims of political struggles.
