Please tell me: Who killed the queen at the end in "The Night Banquet"

In the movie "The Night Banquet", the queen was finally killed by her personal maid Ling'er.

The actor Xu Xiyan, who played Zhang Ziyi's personal maid Ling'er in "The Night Banquet", also explained on her blog:

As the only newcomer in "The Night Banquet", I want to be here I solemnly announce to everyone that Ling'er killed Empress Wan, and Ling'er is me. In fact, there is a detail, I don’t know if you have noticed it, that is, Wanhou took Ling’er to Wuluan’s bathroom, and when she left, there was a handkerchief left behind, and what was painted on the handkerchief was what was going to happen that day at the emperor’s night banquet. thing. I was originally chosen to play Ling'er, and I was very happy because she was also a clue in the script and had a lot to express, but I don't know why many of them were deleted by the director later. Maybe it was too long and there was no way to portray her in such a short time. Let the audience understand so much.

"The Night Banquet" is a palace tragedy film released in 2006. The film is adapted from Shakespeare's famous play "Hamlet" and is directed by Feng Xiaogang. The main actors include Zhang Ziyi, Ge You, Daniel Wu and Zhou Xun. , Huang Xiaoming and other stars. The film tells the story of power, love, and death in palace struggles during China's Five Dynasties and Ten Kingdoms period. It tells people a poignant legend about desire.

The ending of the movie "The Banquet" has been widely debated. When I was watching it, I thought the ending was quite unexpected, and it fulfilled the saying "The mantis stalks the cicada before the oriole follows."

At the emperor's night banquet, all the ministers gathered in the main hall. Qingnv drank the poisoned wine that the queen had stolen for the emperor and died on the spot. When the emperor learned that the woman he loved so much was going to kill him, he drank poisoned wine and died in grief. At this time, his cousin Yin Xuan, who was deeply in love with Qingnv, wanted to kill the queen to take revenge. Unexpectedly, the prince blocked the poisonous sword and Yin Xuan was killed by the queen. In this way, only the queen survived to the end in the hall.

At that time, I was watching the queen in the movie, and I was very moved when I thought of the innocent Wan'er when I was young. The intrigues and intrigues in officialdom can lead to such great changes in people.

Immediately afterwards, only the desire for power and the long-lost queen were left in the hall. At this time, a cold sword suddenly shot through the back of the queen, and finally fell in a pool of blood. In this scene, the movie did not show the person who killed the queen, but only placed an open ending. I think this is what the director wanted to express, that greed will eventually lead to destruction. It seems that he has everything, but in fact In the end there was still nothing.
