The authorities appeared to be trying to set an example with Mr. Luo’s arrest, which was highlighted by state media, including the main television network, CCTV. The arrest — and what appeared to be an orchestrated wave of outrage online — reflected the Communist Party’s prickliness about any efforts to challenge its version of history.
“Some individuals still try to completely deny the War of Resistance against the United States and Aid Korea, question the justice of sending troops, and try to erase the great victory,” a statement that appeared on the social media accounts of the People’s Liberation Army, said, using the Chinese name for the war.
It went on, “No matter how they distort, obliterate, falsify, tease and denigrate the facts, history is written in the hearts of the people.”
According to a police statement, Mr. Luo was charged under a new criminal code that took effect this year, making the defamation of political martyrs a crime. It can result in a prison sentence of up to three years. “Cyberspace is not a lawless place,” the statement said.
Mr. Luo’s account on Weibo was blocked, with the offending post deleted. The police statement said that he had confessed to breaking the law but did not detail what punishment he would face. Mr. Luo could not be reached for comment.
