Jingmn is a prefecture-level city in Guangdong province in southern China with a population of about 4.48 million in 2010. The 3 urban districts are now part of Guangzhou - Shenzhen conurbation. Jiangmen has various alternative romanisations including Kong-Moon, Kongmun or Kiangmoon. The area is alternately referred to as Sze Yup or Ng Yup. The name Jiangmen is often the butt of jokes because its Cantonese pronunciation is identical to the scientific word for anus . One example which came to national attention in early 2012 was a colon cleansing service provider whose advertisement stated: 'We wish the people of Jiangmen to have happy anuses'; Jiangmen residents complained that this slogan was uncivilised and insulting. As a result there have been some proposals to change the name of the city, for example a 2009 proposal to change it to 'Qiaodu' ('City of Overseas Chinese'). The port of Jiangmen, was forced to open to western trade in 1902.
