The United States is entangled in an emotional debate about antisemitism and free speech on college campuses. The latest speech debate in China is about a chef’s video on how to make egg fried rice.

Egg fried rice is a staple of Chinese home cooking and one of the first dishes many Chinese learn to cook. Think of mac and cheese in America. That was probably why Wang Gang, one of China’s most popular food bloggers, has made multiple recipe videos about the dish in the past five years. His “perfect” fried rice recipes attracted reviews, and reviews of those reviews.

Then one of those videos drew the wrath of the official Chinese media and internet.

His offense? He posted an egg fried rice video on Nov. 27, two days after the anniversary of the death of Mao Anying, son of the founder of the People’s Republic of China, Mao Zedong. Mao Anying was killed in the Korean War while, legend has it, cooking egg fried rice.
