Musk was involved in a fight over the Ukraine war with Hujin.
Hu, a former editor-in-chief of Chinese state media outlet Global Times who has been described as China's "troll king" by The Guardian, called Musk out in a Wednesday statement.
Musk asked his followers to vote on whether re-doing the sham referendums in the four Ukrainian regions annexed by Russia would work to bring an end to the conflict.
Hu wrote "Elon Musk has released his personality too much and he believes too much in the US and West's freedom of speech." He will be reprimanded.
Musk responded to Hu with a phrase in Chinese.
A man with his whole hands in his pockets is overly confident according to the Chinese phrase posted by Musk.

It's not clear what Musk meant by the message. It might have been a version of a meme involving an innuendo-laden fake quote from the Chinese philosopher, "Man with hand in pocket feel confident all day."
Users on China's Weibo platform speculated that Musk meant to say that Hu was powerless, even though they didn't know what he was talking about.
Hu responded to Musk on Friday with a message that said: "Man with hands in social media feels confident."

South Carolina Senator Lindsey Graham has sparred with Musk over the last week.
"Fuck off is my very diplomatic reply to you," Andrij Melnyk, the Ukrainian ambassador to Germany, wrote in a reply to Musk. Ukrainian President Volodymyr Zelenskyy took a jab at Musk, asking if people liked Musk who supported Russia or Musk who supported Ukraine more.
Musk got into a heated exchange with the Kyiv Post, a Ukrainian media outlet that called Musk out for his pride and Vanity.
We are thankful to you for the Starlinks. We disagree with your peace plan and make no secret of it, but we would love for you to give us an interview and explain why you disagree with it. We're interested in knowing. On Thursday, the outlet asked its followers to send a message on its account.
Musk said he was not a fan of WW3.
Hu and Musk didn't reply immediately.
