Introduction to the national emblem: This is a national emblem as big as the one hanging on the Tiananmen Gate Tower in Beijing. It is 2 meters in diameter and is made of special metal materials. It is solemn and sacred. That year, Shenyang No. 1 Machine Tool Factory received the task of casting the national emblem. After the hard work of the whole factory, 67 national emblems were successively cast in October 1950 and hung in national government departments and important institutions. Among them, the largest national emblem hangs on the Tiananmen Gate Tower. After more than 60 years of vicissitudes, it is still shining brightly.
