It is mutually intelligible with Cantonese spoken in both Hong Kong and Guangzhou in mainland China but has distinct differences in vocabulary and pronunciation which make it unique.
Cantonese is widely spoken amongst Malaysian Chinese in the capital Kuala Lumpur[1] and throughout much of the surrounding Klang Valley (Petaling Jaya, Gombak, Ampang, Cheras, Rawang, Putrajaya, Selayang, Sungai Buloh, Puchong, Shah Alam, Kajang, Bangi, Semenyih and Subang Jaya) excluding Klang itself where Hokkien predominates.
[5][6] Cantonese is also spoken throughout most of Negeri Sembilan, particularly in the state capital Seremban (but a lesser extent also widely spoken by the local Chinese in other towns of the state such as Jempol, Kuala Pilah, Tampin, Rembau, Port Dickson, Gemas and also Bahau with a special exception in Jelebu, where the Hakka dialect predominates mostly along with the towns of Nilai and Mantin, which are outer suburbs of Seremban city).
[8] Due to its predominance in the capital city, Cantonese is highly influential in local Chinese-language media and is used in commerce by Malaysian Chinese.
The widespread influence of Cantonese is also due in large part to the popularity of Hong Kong media, particularly TVB dramas.
