Yang Guifei was a famous beauty, and there are various theories about her death in history.

Some people say she was buried alive and suffocated to death. Some people say she hanged herself. Some people believe that she was killed by the rebel army, while others believe that she died by swallowing gold. According to historical records, in my opinion, she died by hanging, which is more accurate.
This is a statement that is emphasized in the “Biography of Yang Guifei” in the “Old Book of Tang”, “Zizhi Tongjian” in the “Annals of Tang”, or in the “Song of Everlasting Regret” that we have learned. Emperor Xuanzong couldn’t bear the heavy pressure and, under the pressure of his courtiers, sacrificed his love to protect himself and gave Yang Guifei a white silk. Then Yang Guifei hung herself from the pear tree in the Buddhist temple.
Some people also say that the Noble Consort was killed by rebels, mainly based on some Tang poems. As the line in Du Fu’s poem “Lament for the Head of the River” goes, “Where are the bright eyes and white teeth now? The blood stained soul cannot return.” It implies that the death of the Noble Consort was witnessed by blood. There is also a hint of this in Li Yi’s’ Crossing the Horse’s Wall ‘.

Some people say they died by swallowing gold. However, this statement is based on the speculation in Liu Yuxi’s poem “The Journey of the Horse”.
The love between daughter-in-law and father-in-law has been widely spread. From a peasant girl to a favored concubine. Yang Guifei’s jade ring was also very successful. Some people marvel at the beauty of the Noble Consort, while others marvel at her talent; Some people envy her for monopolizing three thousand graces and her infatuation with a man. So many people don’t want to make her death too tragic. So much so that some people in later generations speculated that the Noble Consort was buried alive, but was soon rescued and smuggled into Japan.
In the TV series “The Legend of the Demon Cat”, Yang Guifei was buried alive. Emperor Xuanzong of Tang was forced by his subjects to kill Yang Guifei, but he himself was unwilling to do so. So I followed a Taoist’s folk remedy and buried the Noble Consort alive first, creating the illusion of a fake death. The result was that the feigned death turned into a real death, and the noble consort had no way to seek help in the coffin. Despite several struggles, she could not escape the fate of being dead and losing her soul. However, this is the effect of a film or television drama, and we have no way of investigating the actual situation.
