The people of Malaysia have a variety of lifestyles. Important among ethnic Malays are respect and obedience toward parents and elders, community self-help, and, in rural areas, the maintenance of law and order through cooperation and respect for the village headman. Marriages, burial customs, and other aspects of Malay life conform to Islamic law. In general, religion plays a major role in each group’s way of life. Wedding ceremonies of ethnic Indians, for example, follow Hindu traditions, whereby the wedding takes place on a day and hour prescribed by a Hindu astrologer. Traditional Chinese family structure is patrilineal and patriarchal; as in China, sons are preferred over daughters in order to maintain the family surname through descent. Kinship ties among the extended Chinese family are very strong and carry into the business environment. Because ethnic Chinese own many Malaysian businesses, these ties hinder occupational mobility among Malays.
