Russian chocolate

Russian chocolate is pure in taste and low in sugar and fat. It is known as "chocolate that can't be eaten fat". It was introduced into China from Russia, and there are many places to buy it in Harbin. Russian chocolate about 9 inches in size can be bought for three or four dollars if you bargain, and for three dollars a piece if you buy more.
