Written in 1940 (with some records suggesting 1936), The Heroes of Tieu Son is Khai Hung's longest and most meticulously crafted masterpiece. Spanning over four hundred pages, this epic historical novel vividly breathes life into a turbulent period of Vietnamese history from over two centuries ago. Set during the transition between the late Le and early Tay Son dynasties, the story unfolds in 1797, during the fifth year of the Canh Thinh reign under Emperor Nguyen Quang Toan. Through rich storytelling and martial arts intrigue, the novel captures the heroic spirits and dramatic struggles of warriors caught in the shifting tides of dynastic change.
