Beijing dialect insofar as pronouncing Manchu sounds was hard for them, and they pronounced Manchu according to Chinese phonetics. In contrast, the Manchus of Aigun, Heilongjiang could both pronounce Manchu sounds properly and mimic the sinified pronunciation of Manchus in Beijing. This was because they learned the Beijing pronunciation from either studying in Peking or from officials sent to Aigun from Beijing. They could also tell them apart, using the Chinese influenced pronunciation of Beijing to demonstrate that they were better educated and had "superior stature" in society. Influence on Mongolian A substantial proportion of the loanwords in Mongolian are derived from Chinese, with the oldest layer of loanwords in Written Mongolian being Chinese in origin. Much of Mongolian spoken in Inner Mongolia has been affected by Mandarin: lexical influence is claimed to be strong in Khorchin Mongolian, whilst there have been claims of phonetic influence from Mandarin Chinese in the Kharchin variety of Mongolian. The aspirated bilabial stop /pʰ/ and the labial approximant /w/ are phonemes only found in loanwords from Chinese and Tibetan, evident in their limited distribution in Mongolian. Substantial diglossia can also be observed in Inner Mongolia. Vocabulary The Beijing dialect typically uses many words that are considered slang, and therefore occur much less or not at all in Standard Chinese. Speakers not native to Beijing may have trouble understanding many or most of these. Many of such slang words employ the rhotic suffix "-r", which is known as erhua. Examples include: – very, especially (referring to manner or attribute) – do not; usually followed by if used as an imperative (usually used when rejecting a favor or politeness from close friends) – to be angry – to leave; to run away – a person with limited abilities, klutz – to let go on feet, to go, leave. / – no backbone, spiritless – to finally and thankfully become quiet and calm – way (to do something); equivalent to Standard Chinese – ruined (especially things to do) - often used in place of , meaning "to go". - often used in place of , meaning "to place". Some Beijing phrases may be somewhat disseminated outside Beijing: – stingy, miserly (used now outside Beijing) – "Excuse me"; heard often on public transportation, from Classical Chinese – to stroll about; equivalent to Standard Chinese or – very; a stronger version of Standard Chinese and believed to derive from
