During the Ming and Qing Dynasties，China was in a continuing turmoil.A lot of people fled to countries that opposed the Qing.Mac Cuu，born in Haikang，Leizhou，with his clansman moved into the Kmir，where they set up a quiet independent regime in which the Chinese made up the main body，and made Ha Tien a prosperous international port.Mac Cuu declared allegiance to the Nguyen Dynasty in Annan afterward.His successor Mac Tien Tu acted as the Qing’s eyes and ears in that war Burma intruded into Siam.At the same time，their regime and Siam were equally matched economically and militarily，they became a major force in Indochina in the 30s and 40s of 18^thcentury.

In ancient Southeast Asia，there were different types of regimes and countries，and some them attached importance to the oversea trade and built the country by the port，which are called the “port states” and have the short governance.If the continent autocratic monarchy countries represented by China which regard Confucianism as the foundation of a nation are considered the classical regime，the regimes which are incomplete and complicated in the political system and the regime’s structure are seen as the non-classical regime.The Mac regime in Ha Tien is representative of the non-classical regime.It only lastde two generations，because the Ha Tien region lacked the foundation for long governing the country and its economic structure is too single and depends too much on ocean，while the multiracial，multi-cultural society structure makes it hard to establish the unified political civilization，society structure and cultural tradition like the classical regime.Like most non-classical regimes in the Southeast Asia，Ha Tien cannot avoid the common destiny.
