Little did they know...
That just a scant few years later, the oppressors would be the Chinese themselves...the "students" becoming radical followers of Marxism, who would deny the citizenry their customs ,food and land in a pogrom worse than any the Japanese could conceive..
In real life,the radical bloodthirsty son would have become a convert,if he wasn't there already, and Jade would have turned The old man and his wife in for their adherance to traditional thoughts and ways.
One would doubt that anything held sacred by the producers of this film (private land ownership,a merchant class and multiple children families)were returned to the peasantry after the defeat of the Japanese.
I am afraid that the ancestral land would have been claimed by the party and turned into a co-operative, where the previous owners would be treated much as the Japanese had treated them..as slaves...
