The Scholars mainly includes Lee Kwang Soo's On the Change of Chongzhen in Two Years, and Yan Chongnian's On Yuan Chonghuan, a national hero who defended Beijing in the Ming Dynasty.

Yuan Chonghuan's murder is also discussed in the relevant chapters of Sun He's A Brief History of the Ming and Qing Wars.

Regarding the death of Yuan Chonghuan, the official view of the Ming Dynasty is that he was punished by the imperial court for his heinous crimes, which were those crimes ordered by Emperor Chongzhen. With the compilation and publication of archives in Qing dynasty, the theory of "double exploration" began to be popular in academia and folk.

In the nearly 300-year history of the Qing Dynasty, many official documents agree with this statement.

At the end of the Qing Dynasty and the beginning of the Republic of China, under the influence of national sentiment and anti-Qing sentiment, people raised Yuan Chonghuan to the extreme, believing that Emperor Chongzhen believed in treachery and killed Yuan Chonghuan by mistake, thus destroying the Great Wall.

Meng Sen has the topic of "Correcting Yuan Chonghuan's False Waste" in the Lecture Notes on the History of Ming and Qing Dynasties, and deeply regrets Yuan Chonghuan's slander and Chongzhen's unkindness. Then, in the preface of Descendants of Yuan Dynasty, it was mentioned that Huang Zongxi was the first person to be killed by a double agent before the Ming History compiled by Qing Dynasty came out.

Lee Kwang Soo's The Truth Before Qing Dynasty holds that the Manchu Jurchen Army is not invincible as stated in the official history book, but has many disadvantages. At that time, the dominant party was always the Ming Dynasty, and it was feasible for Yuan Chonghuan to recover Liaodong in five years. The failure of the Ming dynasty was not due to the lack of national talents, but because the Ming dynasty was dominated by fatuous ministers and uneven hearts. With the help of the Ming court, the Manchu Nuzhen eradicated the talents of the pillars, and took the Liao people as pioneers to escape and destroy the Ming Dynasty.

Articles such as On the Two-year Rebellion in Chongzhen described the battle between Chongzhen and Yuan Chonghuan in prison, arguing that Yuan Chonghuan's rescue made an important contribution to the fight against the post-Jin State, while Emperor Chongzhen trusted him so much that he was deceived into destroying the Great Wall.

In addition, Yuan Chonghuan's murder was also related to the slanderous remarks of Wen Style Ren, Liang Tingdong and other ministers.

Some scholars have further investigated the relationship between Yuan Chonghuan's death and the party struggle in the late Ming Dynasty, and his masterpiece is On the Relationship between Yuan Chonghuan and Lindong Party by Liu Bohan. Liu Jiaoshou thinks that Yuan Chonghuan is closely related to Lindong Party, and his success is closely related to Lindong Party's support. His unjust imprisonment is the result of fierce struggle among Lindong Party, Yen Party and Zhejiang Party.

In recent decades, with the prosperity of the research on the history of Ming and Qing Dynasties, the discussion on Yuan Chonghuan's death finally got rid of the previous linear thinking and gradually moved towards the essence.

Some scholars affirmed that Yuan Chonghuan died of a double agent, the so-called "manslaughter theory". The main papers are Wang's On the Death of Yuan Chonghuan, Xing Di's Wrongful Death of Yuan Chonghuan and the Countermeasures of the Aristocrats in the Later Jin Dynasty, and Yu Dejinhe's Countermeasures of Huang Taiji in the Later Jin Dynasty.

Professor Wang's article affirms the existence of double agents, and thinks that there are two very important factors in Yuan Chonghuan's death: Emperor Chongzhen was ignorant of people and the latter conspired against him. Emperor Chongzhen, traitors and officials of the Ming Dynasty formed a huge alliance to kill Yuan Chonghuan.

Professor Xing's article holds that double espionage is the need of the Ming and Qing Dynasties. At that time, Huang Taiji and the Ming Dynasty wanted to make peace, but they couldn't fight, so they played the trump card of double agent.

The two professors believe that the people who formulated countermeasures were not Huang Taiji and Gao, but Fan Wencheng, who was known as the first counselor of the Qing Dynasty.

Some scholars continue to view Yuan Chonghuan's death from the perspective of party struggle. Representative articles include: Li Shaoqiang's "The Death of Yuan Chonghuan and the Party Struggle in the Late Ming Dynasty" holds that the main reason why Yuan Chonghuan was killed was that Yuan Chonghuan participated in the Party Struggle in the Late Ming Dynasty. Yuan Chonghuan has close political ties with the Party and offended the Party by killing Mao. Therefore, Yan Party intends to use the Yuan Chonghuan incident to promote Dayu, so as to bring down Lindong Party and seize state power.

Zhang Dexin's "Yuan Chonghuan's Death and Party Struggle in the Late Ming Dynasty" holds that Yuan Chonghuan's fate has always been closely linked with the Party Struggle in the Late Ming Dynasty, and his death is a historical tragedy evolved by the remnants of the Zhen Shi Group using the headstrong, suspicious and reneging character of Emperor Chongzhen.

Most scholars believe that the feud between Xu Jin and the imperial court is only the reason why Yuan Chonghuan was imprisoned, not the real reason why he was killed. Yuan Chonghuan's death is the result of interaction between social factors and personal factors.

One view is that the decision of Yuan Chonghuan's imprisonment lies with Emperor Chongzhen, and it is advocated to find the cause of Yuan Chonghuan's death from the relationship between Emperor Chongzhen and Yuan Chonghuan. In their view, the feud between the two sides was just an external cause, and it was because of the suspicion and confusion of Emperor Chongzhen that Yuan Chonghuan's unjust case was caused. Their views can be divided into two types: coma theory and avoidance theory.

Yan Chongnian is the representative of "Confusion and Violence Theory". In On Yuan Chonghuan, he thinks that the reasons why Yuan Chonghuan was imprisoned and killed are different. The reasons for imprisonment are rebellion, resentment of Chinese people, framed by political enemies, and stubborn Chongzhen.

He was killed because of post-Xu Jin hatred, resentment towards Chinese people, dissatisfaction with powerful people, old grievances of colleagues, jealousy of castration and ignorance of Chongzhen. The analysis of Yuan Chonghuan's death further points out that the contradiction between Yuan Chonghuan's aloof and upright character and Emperor Chongzhen's headstrong and violent character is the internal and real cause of Yuan Chonghuan's death.

The representative figures of the theory of avoiding killing are Simon Lu's On Avoiding Killing Yuan Chonghuan in Ming Dynasty and Yan's analysis of Yuan Chonghuan's death.

Professor Lu thinks that the theory of manslaughter can't be justified, but it is actually an excuse for Emperor Chongzhen and a eulogy for the Qing Dynasty. He thinks that Yuan Chonghuan was killed because of the suspicion of Emperor Chongzhen. Under the tyrant Emperor Chongzhen, being killed is an inevitable result.

According to Professor Yan's article, from the point of view of the relationship between monarch and minister, the fundamental reason why Yuan Chonghuan was killed was that his actions with the Party hindered the autocratic rule of Emperor Chongzhen, so Emperor Chongzhen deliberately killed him.

Other scholars disagree with the theories of "being careless" and "avoiding killing", and attribute Yuan Chonghuan's death to the unkindness of Emperor Chongzhen, and think that Yuan Chonghuan's death has his personal unshirkable responsibility.

In their view, Yuan Chonghuan was re-appointed as the governor of Liao Dynasty, and there were a series of military mistakes. The boasting of "Reviving Liao in Five Years" and the change of previous dynasties made Yuan Chonghuan a tragedy.

The representatives of this view are Li, Yu Sanle, PG One and others. According to Li's "The Covenant of Reigning Liao in Five Years", Yuan Chonghuan's death was due to the bankruptcy of the Covenant of Reigning Liao in Five Years. Although he has his own experience, he has a strong ideal color, which is related to Yuan Chonghuan's character defect.

In On Yuan Chonghuan's Personality, he further analyzed the advantages and disadvantages of Yuan Chonghuan's personality and its evolution, and thought that his weakness led to his tragic ending.

Yu Sanle's Death of Yuan Chonghuan also thinks that Yuan Chonghuan put forward the wrong strategy of restoring Liao for five years because of his pride and underestimation of his enemy. After he went through the customs, he made three major mistakes, one about the Siraqin department of Mongolia, the other about the defense of Jiyumen, and the other about slaying Mao and Dongjiang.

The Emperor Chongzhen and Yuan Chonghuan written by PG One thinks that the five-year commitment to pacify Liao and the past changes are enough to put a rope around Yuan Chonghuan's neck, and the personality characteristics of Emperor Chongzhen and the theory of facing the DPRK led to Yuan Chonghuan's murder.

In academic circles, Yuan Chonghuan's research data on the cause of death is vast, and scholars' statements have their own reasons and defects. The topic of Yuan Chonghuan's death will continue to be discussed.
