It was when President Kim Il Sung dropped in at a house on his field guidance to Sinchon County, South Hwang
Acquainting himself in detail with living situations with parental love, the President asked owner of the house about his monthly income and the price of soybean paste and sauce and rice.
He failed to answer the President’s unexpected question.
As if to relax him, the President said with a laugh that he might have no idea about them and it was good. Then the President explained that the price of soybean paste and sauce were so and so and the price of rice and salt were so and so and thus the total amount to be spent by the owner would be so and so.
Soon afterwards, the President told accompanied officials that householders might have no idea about them but officials at power organs should know them all.
