Zhang Xiaolin was known as "Zhang Dashuai" and "Three Color Tycoon" in the turbulent old Shanghai. He comes from a lower social class, but he has been able to dominate Shanghai for decades and become a "famous figure" in the gang, which shows his brilliant methods. He haunts the three lanes of "yellow, black, and white". He runs brothels, sells tobacco, and sets up casinos. He is good at everything. He wooed the Beiyang warlords and important officials of the Kuomintang, and became brothers with high-ranking military and political officials. He was like the "White Prime Minister." He forgot his ancestors, betrayed his country for glory, acted as a lackey of the Japanese, and became a notorious traitor. His complex character and ups and downs of life experience are nothing less than a microcosm of the world and even this special historical period.
