A The Old-School Underworld: The Last Arbiter
A life spanning Japanese Rule × Postwar Era × Martial Law
A footprint crossing Taiwan × Japan × China

Tsai Chin-tu and a century of Taiwan's underworld amidst the tides of history.

From his origins as "Seng-ko" on the streets to becoming one of Taipei’s first elected city councilors, Tsai Chin-tu’s life offers the ultimate key to understanding the Taiwanese and Japanese underground societies before and after WWII—representing the final, legendary silhouette of old-school outlaw honor.

A gathering of titans: At his funeral, political elites, business moguls, and underworld figures from both Taiwan and abroad came to pay their respects.

A formidable reputation: His name alone held enough authority to guarantee peace and order at high-stakes shows for legendary Taiwanese opera icons Yang Li-hua and Yeh Ching.

A history-making life: His story directly intersects with major historical figures, including Chiang Kai-shek and his son Chiang Ching-kuo, former Japanese Prime Minister Kakuei Tanaka, and prominent political figure Koo Kwang-ming.

Living through both the Japanese colonial period and the Martial Law era, Tsai was a local community leader, a patron of traditional folk arts (Yizhen), and an indispensable mediator between civil society and political power. Deeply enmeshed in cross-border Taiwan-Japan relations while regularly arbitrating complex underworld disputes, the media struggled to categorize him—ultimately settling on the evocative title: "Taipei’s Prominent Figure."
