There were also many supporters of Jiang's promotion, saying that what she did showed she is a good public servant.
Su, the Jiangyou official, applauded the debate, saying "it shows the public are concerned on promotions of government officials and their enthusiasm for politics."
However, he said "we have gone through due procedures and believe she is qualified for her new post."
Jiang, 30, a mother of a six-month old, left her own baby with her parents and took part in the disaster relief work after the Sichuan quake.
Moved by the plight of babies separated from their mothers, she ended up breast-feeding nine of them. The pictures of her breast feeding spread across the country, which earned her a nickname "the police mum."
She has since been awarded laudatory titles of "hero and model police officer" and "excellent member of the Communist Party" by the Ministry of Public Security and the Organization Department of the CPC Central Committee.
