The City's Name
Again, the name is quite diverse and it is more easy to quote from Wikipedia.org:
"Aksu (also known as Ak-su, Akshu, Aqsu, Bharuka and Po-lu-chia. Uyghur: ئاقسۇ/Ak̡su; simplified Chinese 阿克苏, traditional Chinese: 阿克蘇, pinyin: Ākèsù) is a city in the Chinese province of Xinjiang and the capital of Aksu Prefecture. The name Aksu literally means white water, and is used for both the town and the river."
