The full text under the picture:
A red sun rises in the east, and the huge crowd cheers with thunder. Our most beloved leader Chairman Mao and his close comrade-in-arms Comrade Lin Biao, full of energy and in high spirits, reviewed the ranks of young revolutionary generals on the Tian'anmen rostrum. Chairman Mao's good health is the greatest happiness for all the people of China and all the people of the world.
一輪紅日东升,万众欢声雷动。我們最敬爱的領袖毛主席和他的亲密战友林彪同志,精力充沛,神采奕奕,在天安門城楼上檢閱革命小将的队伍。毛主席的身体这样健康,是全中国人民和全世界人民最大的幸福。
