That day, he dropped in at the sample room and saw different kinds of children's foodstuffs produced at the factory one by one before saying:
  Now that the production processes have been modernized and the product analysis system established, it is necessary to compete with other countries in taste.

  His precious instructions implied what the standard should be in appraising the products of the Pyongyang Children's Foodstuff Factory.
