Basically the town is exsited for soldiers. In the place, you can see the a lot of soldiers walking around; most of soldiers in Kinmen are from Taiwan, therefore, they come to Shanwai to shop for their daily equipment. On Sundays, it's the only time soldiers are on leave in Kinmen, during the period, you can ADMIRE how many of us are here in Kinmen.
As I mention in the last paragraph, you can buy all the things you need from souvenir to lunch box. If you come to Kinmen in a rush, please do pay a short visit to Shanwai...You will not regret FOR SURE!!!
For most of soldiers in Kinmen, they (we) like to waste our time in Internet Cafe since they have nothing much to do. This one is our fave, you can always find someone from my unit. The pirce here perfectly suits to soldiers' holiday, from Monday to Saturday, the price is about NT20~35, on Sundays you have to pay at least 40.
