1968165438+1October 25th stamps were first issued in Beijing, and the issuing time was less than half a day. An editor of China Map Publishing House found that the map of China on this stamp was not accurately drawn, nor were the Xisha Islands and Nansha Islands drawn. He reported to the Ministry of Posts and Telecommunications through the organization. After discovering the problem, the Ministry of Posts and Telecommunications urgently ordered post offices all over the country to stop selling and return all stamps. However, some post offices have sold this stamp in advance, resulting in a small number of stamps flowing out. "A Piece of Red" has become a famous rare stamp in New China and ranks among the rare stamps in the world.
