During the War of Resistance Against Japanese Aggression (1931-45), he quit all his business positions to focus on fundraising in the Americas to support the fight to defend the motherland.
A donation check written by him during the war is on display at the exhibition, which runs until May 3.
In the later Chinese civil war, Situ chose to side with the Communist Party against Kuomintang rule.
Also on display at the exhibition is a coat presented to him by Premier Zhou Enlai, showing his close friendship with Communist leaders.
"Situ experienced many crucial moments in recent Chinese history. But he chose the progressive position each time and set an example for future generations," Qi says.
"We admire his contributions and overseas Chinese efforts will continue to contribute to the rejuvenation of the Chinese nation."
