One day in May 1993, President Kim Il Sung met a party delegation of an African country who came to Pyongyang to learn from the Workers' Party of Korea’s party building experience. The members of the delegation asked the President what is the ideal way of building a ruling party. Then he picked up a peach from the table and gave a clear answer that the party should be thoroughly built like the fruit. Pointing to the peach in his hand, he said: Only when the single-hearted unity of the leader, the party and the masses is achieved, can the revolution and construction be carried out successfully. Figuratively speaking, the flesh of this peach is the masses of the people, its stone is the party and the kernel in the stone is the leader. Citing the mango of Africa without kernel, the President said that a unity should not be the one without kernel like a mango.
