The political campaigns from 1950s to the end of 1970s in china made many unjust cases,many honest men were ruthlessly persecuted. Only a few of powerful victims got economic compensation after Deng xiao-ping came to power, most of the common victims got nothing till now.
we know it's a just cause to protecting human rights and punishing crime. German government reflected on its antihuman crime, made economic compensation to the Jewish victims who were persecuted by nazi during WWII in the past few decades.
As the biggest and most powerful democratic country in this world, we appeal US government push chinese authorities,as a modern civilized country's government, to take its responsibility!!!
