BEIJING — A labor arbitration panel in the southwestern Chinese province of Guizhou ruled on Tuesday against a transgender man, the plaintiff and his lawyer said, in what has been described as the country’s first transgender job discrimination case.

The plaintiff, 28, who has been identified in Chinese state news media only as Mr. C and has declined to provide his real name out of privacy concerns, was born a woman, but has said he considered himself a man and has worn men’s clothes since college. He filed his case in March with a labor arbitration committee in Guiyang, the provincial capital, after the Ciming Health Checkup Center dismissed him last year after a brief probation period on the grounds that he dressed like a gay man and would strike customers as “unhealthy,” Mr. C quoted a human resources manager as saying in an earlier interview.

The panel ordered the company to pay Mr. C 402.30 renminbi, about $61, as Mr. C’s wage for his one-week probation period, and rejected his demand for an additional month’s pay, about 2,000 renminbi, as compensation and a written apology, Mr. C’s lawyer, Huang Sha, said in a telephone interview.

In a text message, Mr. C said he was disappointed by the ruling and would file a court case soon.

“Although I got the wage, but that wasn’t what I have wanted at all,” he said. “In the process of this case, I learned that discrimination against gender expression and transgender individuals is even more serious than I imagined. I hope the law wouldn’t keep supporting discrimination.”
