What is the final ending of The Biography of Princess Gong Chun of Yan Xi?

The story of Yan Xi Palace Chunfei was finally strangled in the cold palace by kite string.

The queen went to the cold palace to visit the pure imperial concubine, who was anxious to ask what role the queen played. The pure imperial concubine was furious and claimed that the queen let herself die step by step, but there was no evidence to prove it. Many things are the queen's career. She killed seven elder brothers, forced the queen to commit suicide first, lured herself into a life-and-death struggle with Wei wreaths, and finally took rolling in the deep by wreaths. But the queen's hands are clean from beginning to end. The queen said that because her voice was too hypocritical, she just wanted to stay with the emperor, being bullied and seduced again and again, being caught between peace and height, and being out of breath. Who can bear this pain? It is obvious that they are heartless, but they mean what they say. This is a big joke. Chun Guifei committed suicide. The news of Chunguifei's death spread all over the harem. Because of the kite string, everyone will suspect that Luo Zhang killed Chunguifei.
