Jinjiang, Fujian in the context of "Nan'an, Fujian"

The Penghu (/ˈpʌŋˈhuː/ PUNG-HOO, Hokkien POJ: Phîⁿ-ô͘  or Phêⁿ-ô͘ ) or Pescadores Islands are an archipelago of 90 islands and islets in the Taiwan Strait, about 50 kilometres (25 nautical miles) west of the main island of Taiwan across the Penghu Channel, covering an area of 141 km (54 sq mi). The archipelago collectively forms Penghu County. The largest city is Magong, on the largest island, which is also named Magong.

The Penghu islands first appear in the historical record in the Tang dynasty and were inhabited by Chinese people under the Southern Song dynasty, during which they were attached to Jinjiang County of Fujian. The archipelago was formally incorporated as an administrative unit of China in 1281 under Tong'an County of Jiangzhe Province in the Yuan dynasty. It continued to be controlled by Imperial China with brief European occupations by the Dutch Empire (1622–1624) and Second French colonial empire (1885), until it was ceded to the Empire of Japan in 1895. Japan’s surrender in 1945 ended its colonial rule over the Islands, which has since then been governed by the Republic of China (ROC). Under the terms of the Sino-American Mutual Defense Treaty and the subsequent Taiwan Relations Act between the ROC and the United States, Penghu is defined and geographically acknowledged as part of Taiwan.

Quanzhou is a prefecture-level port city on the north bank of the Jin River, beside the Taiwan Strait in southern Fujian, People's Republic of China. It is Fujian's most populous metropolitan region, with an area of 11,245 square kilometers (4,342 sq mi) and a population of 8,782,285 as of the 2020 census. Its built-up area is home to 6,669,711 inhabitants, encompassing the Licheng, Fengze, and Luojiang urban districts; Jinjiang, Nan'an, and Shishi cities; Hui'an County; and the Quanzhou District for Taiwanese Investment. Quanzhou was China's 12th-largest extended metropolitan area in 2010.

Quanzhou was China's major port for foreign traders, who knew it as Zaiton, during the 11th through 14th centuries. It was visited by both Marco Polo and Ibn Battuta; both travelers praised it as one of the most prosperous and glorious cities in the world. It was the naval base from which the Mongol attacks on Japan and Java were primarily launched and a cosmopolitan center with Buddhist and Hindu temples, Islamic mosques, and Christian churches, including a Catholic cathedral and Franciscan friaries. A failed revolt prompted a massacre of the city's foreign communities in 1357. Economic dislocations—including piracy and an imperial overreaction to it during the Ming and Qing—reduced its prosperity, with Japanese trade shifting to Ningbo and Zhapu and other foreign trade restricted to Guangzhou. Quanzhou became an opium-smuggling center in the 19th century but the siltation of its harbor hindered trade by larger ships.
