  <title>Chinese Education From a Western Viewpoint</title> 
  <longdesc>I find this to be an interesting book. Through Yen Sun Ho's comparison of Chinese education to European and U.S. education, he provides a snapshot of education in 1912. Of particular interest to me was the comparison of the cultures and philosophies that surrounded these educational systems.</longdesc>
