Yanji (延吉) is a city in Jilin Province.
Koreans first migrated to the Yanji area after a series of famines struck in 1869. The area, called the Yanbian Chaoxianzu (Korean) Autonomous Prefecture, is the home of the largest group of ethnic Koreans living outside of Korea, and most of the Koreans here hold Chinese, not Korean citizenship. Since large areas of Yanbian were off-limits to travelers, the tourist facilities and people who speak English are kind of non-existent at the moment but that is changing.
Unlike other Chinese cities, this little city is relatively clean and peaceful. You can find quite many cafes for this little city where serves good coffees and also you will see many tea houses (茶坐) around the city.
Internet access While there is plenty of internet cafes around you will be required to have a Chinese ID in order to use them. A foreign passport will not suffice unless you get lucky. The easiest way to get access may therefore be to get a hotel room which provides it.
