I think that learning about the world history is better than learning about your country, so I disagree with this statement. Everybody knows that learning about the country's history make they feel happy and confident about their country. We are living in the 4.0 era, an era where all people are fair and all peoples can live in peace. Or at least I hope so.  But one thing everyone needs to recognize is that there is no more racism.And we study World History to know how beautiful the world is, how brave everyone was to overcome difficulties.Don't just study our country's history, but discriminate against other people in another country because that country made war with our country in the past. It's important to study your country's history. It's important to study world history. Don't underestimate either of these two types of history.Learn history for a good purpose and don't be angry with anyone because everything is over.
