In Shanghai in 1929, banker Han Chenyi and progressive student Lin Beiyu first formed prejudices due to ideological conflicts. In the flames of the Anti-Japanese War, they experienced the test of life and death in Wuhan, the years in Chongqing, and the relocation of industry, and they moved from antagonism to understanding. Reunited in Shanghai after the war, the two became spiritual partners amidst the clouds of inflation and civil war. In 1949, they jointly chose to stay and face the new era. After thirty years of ups and downs, they have always protected the original intention of "making China better" in different ways, and finally passed on the shimmering spirit to the new generation, completing the relay of faith between the two generations.
