Abstract：：Malaysia is a multi-national and multi-cultural country. In such diversified social background, the linguistics scenery there are also multiple. During the colonial period, the British colonial government took English as the official language, while all the nations clung to their own languages. This leads to the lack of basis for national integration after the independence. In order to solve this problem, the Malaysia government set out language planning activities and language policies, and finally establish and consolidate the national language and sole official language status of the Malay language.
