Yang Qianghua, who lives in Germany, is one of the hundreds of overseas Chinese invited to attend the event.
He says the younger generation tends to forget the sacrifices made during the war.
"Seventy years ago, our older generation, including those overseas, made huge sacrifices and great contributions to national independence and liberation, as well as to world peace and justice. We should cherish the memory of the revolutionary martyrs and their fight for world peace, and never forget history. So I think this commemoration is very significant."
