In June 1950, Mao requested to join the Chinese People's Volunteer Army (PVA) as an officer in the Korean War. PVA commander Peng Dehuai and other high-ranking officers, fearing Mao Zedong's reaction if his favorite son was to be killed in combat, had long opposed allowing Mao to join the PVA and tried to prevent him from entering. Mao Zedong overrode Peng, who allegedly shouted, "He is Mao Zedong's son. Why should it be anything else?" Peng instead had Mao assigned to himself as his secretary and Russian translator, under the pseudonym "Secretary Liu" at the PVA headquarters, located in caves near an old gold mining settlement in Tongchang County. This location offered excellent protection from United Nations (UN) air attacks and was far from the front lines of the war.[4][6] However, the safety was an illusion, as the US Air Force completely controlled the airspace.[7]

On the evening of 24 November, two UN aircraft, P-61s on a photo reconnaissance mission, were seen overhead.[8] According to multiple Chinese eyewitnesses, sometime between 10:00 am and noon on 25 November, four Douglas B-26 Invaders dropped napalm bombs in the area.[9][10] One of the bombs destroyed a makeshift building near the caves, killing Mao and another officer, Gao Ruixin. Several conflicting reasons have been given as to why Mao was in the building, including suggestions that he was cooking food during daylight, in violation of Chinese Army regulations,[1][8][11] fetching documents, or sleeping late due to night duties,[9] which had led to him missing breakfast.[12] Another reason given was that due to the high amount of communications, being the PVA headquarters, the Americans were able to combine aerial reconnaissance with the direction of radio waves, to identify its location.[13]

Peng witnessed the explosion nearby and, realizing Mao was in danger, tried to run towards him but was physically restrained by his guards. Peng screamed, "if you don't let go, I'll kill you!" to which the guard responded, "if you kill me, I still won't let go".[14] Mao's body was reportedly burnt beyond recognition and was only identifiable through a Soviet watch given to him by Joseph Stalin. Peng immediately reported Mao's death to the Central Military Commission, but Zhou Enlai, Liu Shaoqi, and Yang Shangkun ordered the CMC and Politburo not to inform Mao Zedong. Only in January 1951, when Mao Zedong asked his personal secretary Ye Zilong to have Mao transferred back to China, Ye informed him of the news.[citation needed] Mao was buried in Pyongyang, in the Cemetery for the Heroes of the Chinese People's Volunteer Army.

Some Chinese citizens and groups who oppose Mao Zedong commemorate the anniversary of Mao Anying's death by eating egg fried rice. According to some sources, on the morning of 25 November 1950, Mao Anying, alongside staff officers Gao Ruixun and Cheng Pu, cooked egg fried rice for breakfast in the office of Peng Dehuai, despite orders only to cook at night for fear of American air raids. It is alleged that their preparation of that meal drew the attention of American bombers, contributing to the deaths of Mao and Gao.[15][16]

The fried rice story of Anying's death has never been confirmed. The Chinese Academy of History, a state-run historical research institute set up in 2019, had denounced the story as rumors spread by those who aimed to disrespect Mao Anying's sacrifice to his country. The academy, citing declassified documents, stated Mao's position was compromised when the camp's radio transmissions were being intercepted.[17][18]

"Egg fried rice protests" are a form of internet protest used by Chinese users occurring yearly around 24 October, Anying's birthday, or around 25 November, the date of his death. Posting recipes for egg fried rice is meant to mock the death of Anying; such posts are usually blocked or taken down by Chinese officials and can lead to sanctions against those involved.[15]
