North and west. Xinjiang is China's westernmost province, bordering various 'stans'. - Kazakstan, Kyrgystan, Tajikistan, Afghanistan, Pakistan and India. It also borders Mongolia to the north and Tibet to the south. The local language is more Turkic than Chinese. Great food!
船儿 (chuàn ér) is the common name in Beijing where they liked to stick 'er' on many words.
