Set of 50 volumes to learn more about the world we need to know betterPrejudice and prejudice are no knowledge! Publishers of my life are a world of prejudiced worlds To provide more precise information and knowledge, we are planning to publish three series of The Culture that we should know better about the world. This series was commissioned by leading experts in each field to translate and provide more accurate information to the teachers of the national social group. We wanted to let our children know that if everyone cares about the fact that A is B, it is a fact that A can not be B but C or D. . Through this, we want to help our children to gain the right view of the world, and to enjoy the intellectual pleasure of knowing the truth.
