full_context: Document 1: Ghosts (2006 film): Ghosts is a 2006 drama film directed by Nick Broomfield, based on the 2004 Morecambe Bay cockling disaster. The title is a reference to the Cantonese slang term "Gweilo" (鬼佬), meaning "ghost man", used for white people.
Document 2: Westernised Chinese language: Common Chinese-language errors by non-native learners of Chinese (sometimes called Westernised Chinese ()), usually refers to a pattern of written or spoken Chinese language, characterised by the significant influence from European languages, with regards to grammar, vocabulary, syntax and word order. Influences from English are particularly noticeable, especially in translations of literary works and documents in English. Westernised Chinese lacks the characteristics of traditional Chinese writing, and sometimes poses reading or understanding difficulties to readers because of its awkwardness and/or wordiness. It is probable that most Westernized Chinese translations are a very direct translation from English into Chinese by native Chinese speakers, given the virtually non-existent demand for native English speakers to perform written translation into Chinese. In the first half of the 20th century, Lu Xun advocated that translations of Western works into Chinese closely follow the Western structure, but Lu Xun's arguments failed to be persuasive, and translators subsequently used a more natural translation style from English to Chinese.

They may be distinguished from ethnic or religious slurs in that they do not necessarily designate a specific group, and instead target all who do not belong to a specific group.
