This combination of Sun's own words with journalistic evidence to provide both subjective and objective views was extremely well received. But in fact there are very few examples of objectively critical authorized biographies of "big league" politicians. Most authors wishing to write about political figures adopt the second-best approach of collecting material indirectly in a round-about "covert operation."
但能獲得「重量級」政治人物正式授權，並以第三者客觀立場寫評傳的例子畢竟不多，多數有意以政治人物為題的作者，只有退而求其次，採取「旁敲側擊」的方式。
