Light, tasty and simple to make, egg fried rice has long been a beloved dish in China and one of most recognizable icons of Chinese cuisine around the world.

But in recent years, the popular stir-fry has become a highly sensitive subject for China’s online nationalists, especially around the months of October and November.

Emotions are running so high this week that one of the country’s most famous chefs has been forced to apologize – for making a video on how to cook the dish.

“As a chef, I will never make egg fried rice again,” Wang Gang, a celebrity chef with more than 10 million online fans, pledged in a video message on Monday.

Wang’s “solemn apology” attempted to tame a frothing torrent of criticism about the video, which was posted on Chinese social media site Weibo on November 27.

Angry nationalists accused Wang of using the video to mock the death of Mao Zedong’s eldest son, Mao Anying, who was killed in an American air strike during the Korean War on November 25, 1950.
