Under the lottery rules, applicants who fail to win in two months are automatically re-entered in subsequent drawings. Given the number of new applicants each month, the odds of winning have been decreasing.
In October, one out of every 59 applicants won a registration, and in November, 67 applicants competed for a car registration certificate.
As the end of November, there were more than 1.67 million individual applicants.
The lottery is carried out on the 26th day of every month.
Lu Jun, who works at a public relations company in Beijing, said he has participated in the lottery every month since May 2011.
"I have been trying my luck, but I have been disappointed each time I checked the results," the 29-year-old said. "I think my chances of winning would be better if I were to change my name to Liu Xuemei."
The name Liu Xuemei appeared in the car registration winning lists for seven straight months from May to November.
The Beijing Municipal Commission of Transport posted an article on its website on Nov 29 denying people's suspicions that the lottery is rigged.
The commission said it was a coincidence, and that many applicants have the same name.
