The Chinese / English bilingual edition of the history series How America Became America added authentic Chinese translation to the succinct and compelling original text in English. Also a great language learning tool to help children learn either Chinese or English by studying the American history. The 13-book series introduced how the birth and growth of the United States was shaped by centuries of thinkers and events. The 4th book of the series focuses on Thomas Jefferson, one of the most important of these thinkers. During his presidency, the Louisiana Purchase doubled the geographic size of the United States. And perhaps most important, Jefferson helped define what is best about America.
