Since it’s a Chinese movie, I think it’s better to comment on it in Chinese. However, it’s followed by an English translation.
The Confucian said, "of all the people, women and servants are the most difficult to behave to. If you are familiar with them, they lose their humility. If you maintain a reserve towards them, they are discontented", which indicates that women often change their minds, but from my point of view, that’s not the case. The hearts of women are not, as the meddlesome say, visional like the flower in the mirror and transient like the moon in the water, they are the same as that of the men. The reason why they are seldom comprehended is the existence of the androcracy. The men are above the women, and treat them as if they were so docile, but men are over conceited on this, had the Queen Chen(aka A-Jiao) of of Han Dynasty a dagger in hand, the Emperor’s situation would be in serious danger. Back to the movie, the coup Emperor first raped the Queen mentally and later the body, so the seed of hatred was naturally and consequently planted in her brain.The coups by the Emperor Wu Ze-tian of Tang Dynasty and Empress Dowager Ci Xi of the Qing Dynasty were not accidetns, they were the fallouts of the androcracy in China’s society. Being one of the thousands of concubines, one had to be crafty to survive the system, or it would devour her, just like the old Chinese adage says "Every man for himself, and the devil takes the hindmost". The movie has over emphasized on the evilness of human nature, which’s bullshit, it’s normal to have an evil heart when in such a turmoil, which was reckoned by my ancient Chinese fellows as the aftermath of the failure on moral education, but I think the failure of the system was the true reason.
