With China stumping assertively on the world stage, one might think Beijing would be open, even gracious, about the country's past. To the contrary, history remains an exceedingly sensitive subject here, drawing relentless attention from authorities anxious to keep all skeletons safely in closets.

What they do know tends to agree with government-sponsored discourse on the pride and glory of China's rise after a century of humiliation by Western powers.

Library and bookstore shelves tell, with enviable conviction, this same story of national grandeur. And it is hard to get around that government-approved tale.
