Who is the outdoor poo in ApRok river for?

Who is the outdoor poo in ApRok river for? Nkorea is building an out door pool in the north of ApRok riverside. it shows Nkorea is changing. Especially, there are chinese cruises passing at a little(about 30~40m) way off from the pool. Nkorea is propagating they are making several amusement parks in all over the country as a part of 'Prioritizig to love the the north korean people' but it is just a show and nothing to do with people's living. In fact, there is an amusment park near the pool but it is opened in the special days only like kim il sung, kim jong il, kom jong un's birth day. Who these facilities are for?
