1757年（清乾隆二十二年），宣佈廣州為全國唯一對外通商口岸，史稱“一口通商”，全中國對外貿易指定由廣州十三行代理。“一口通商”令當時嘅廣州（歐洲商人稱Canton）得以獨攬全國外貿，國際知名度迅速提高，成為世界第三大城市（當其時次於北京，倫敦之後），係廣州最輝煌嘅時期之一。
In 1757 (the 22nd year of Qianlong in the Qing Dynasty), Guangzhou was declared the only foreign trade port in the country, known as "one-port trade" in history, and the foreign trade of the whole China was designated by the 13 banks of Guangzhou. As a result of the trade of Canton, which was known to European merchants at that time, Guangzhou (known as Canton in Europe) was able to monopolize the country's foreign trade, and its international popularity increased rapidly, becoming the third largest city in the world (after Beijing and London at that time), which was one of the most glorious periods of Guangzhou.
