One example of the complexity with which Malaysia's immigrant populations have contributed to the nation's culture as a whole is the history of Chinese immigrants. The first Chinese to settle in the straits, primarily in and around Malacca, gradually adopted elements of Malaysian culture and intermarried with the Malaysian community. Known as babas and nonyas, they eventually produced a synthetic set of practices, beliefs, and arts, combining Malay and Chinese traditions in such a way as to create a new culture. Later Chinese, coming to exploit the tin and rubber booms, have preserved their culture much more meticulously. A city like Penang, for example, can often give one the impression of being in China rather than in Malaysia.
