Yingkou was historically known asNewchwang (Chinese:牛庄;pinyin:Niúzhuāng;Manchu: Ishangga gašan hoton) inpostal romanization; it was one of theTreaty Ports opened under theTreaties of Tianjin of 1858. In fact, the actual town of Newchwang was about thirty miles upstream ofLiao He, within today'scounty-level city ofHaicheng. After the treaty had been signed, the British found that the river near Newchwang was too shallow for their ships. Instead, the treaty port was moved to the area nearer to the river mouth where today's Yingkou is located.
To avoid confusion between the two locations, careful English writers of the early 20th century would sometimes useNewchwang for Yingkou (explaining that "Ying-kow, ... outside Manchuria, ... is known only as Newchwang") andNiu-chuang (the properWade–Giles transcription of '牛庄') for the actual inland Niuzhuang Town.[5] Meanwhile,Newchwangcheng (牛庄城;postal:Newchwang Town) was adopted by the government as the inland town's name to distinguish it from the coastal city.
