Problem: Montevideo:

Montevideo is situated on the north shore of the Río de la Plata, the arm of the Atlantic Ocean that separates the south coast of Uruguay from the north coast of Argentina; Buenos Aires lies 230 kilometres (140 mi) west on the Argentine side. The Santa Lucía River forms a natural border between Montevideo and San José Department to its west. To the city's north and east is Canelones Department, with the stream of Carrasco forming the eastern natural border. The coastline forming the city's southern border is interspersed with rocky protrusions and sandy beaches. The Bay of Montevideo forms a natural harbour, the nation's largest and one of the largest in the Southern Cone, and the finest natural port in the region, functioning as a crucial component of the Uruguayan economy and foreign trade.

Problem: Hokkien:

Xiamen dialect, sometimes known as Amoy, is the main dialect spoken in the Chinese city of Xiamen and its surrounding regions of Tong'an and Xiang'an, both of which are now included in the Greater Xiamen area. This dialect developed in the late Ming dynasty when Xiamen was increasingly taking over Quanzhou's position as the main port of trade in southeastern China. Quanzhou traders began travelling southwards to Xiamen to carry on their businesses while Zhangzhou peasants began traveling northwards to Xiamen in search of job opportunities. It is at this time when a need for a common language arose. The Quanzhou and Zhangzhou varieties are similar in many ways (as can be seen from the common place of Henan Luoyang where they originated), but due to differences in accents, communication can be a problem. Quanzhou businessmen considered their speech to be the prestige accent and considered Zhangzhou's to be a village dialect. Over the centuries, dialect leveling occurred and the two speeches mixed to produce the Amoy dialect.

What city took over Quanzhou's position as the main port of trade in SE China?
