After the exchanges between the Quanzhou dialect and the Shuozhou dialect in each other's residents, the "Xiamen dialect" was produced and became the representative language of the original "Mandaan dialect" in southern Anhui. By the same token, after the Dutch occupied Taiwan in 1624, in order to gain economic benefits, they sent people to Fujian and Guangdong to recruit immigrants to Taiwan to open up. Minnan dialect also came to Taiwan. In 1662, Cheng Chengpower led the tens of thousands of troops who lived along the coast of Fujian. They came to Taiwan to drive away the Dutch. These two large immigrants brought the Quanzhou and Zhangzhou dialects of Fujian to Taiwan. This is the predecessor of the current Taiwanese dialect. The current "Lukang Chamber" is to preserve the more pure "Quanzhou dialect", while the "Yi Lancao" retains the pure "Zhangzhou dialect". Residents in other parts of Taiwan have formed a so-called "small and prosperous" due to long-term coexistence and language exchange. At present, the northern part of the country is full of sounds, and the southern part of the country is "small springs". Therefore, it is also a mixed sound of 漳 and spring. It is called "Xiamen" in the southern part of China and "Taiwanese" in Taiwan.
