On July 1, 1967, the Ministry of Posts and Telecommunications issued a set of stamps to commemorate the 46th anniversary of the founding of the Communist Party of China under the title of "Wishing Chairman Mao a Long Life without Frontiers."
Originally, one of the principles for selecting topics determined by China's stamp issuing department before the "Cultural Revolution" was to issue stamps every tenth or friday on major commemorative festivals. In 1967, the 46th anniversary of the founding of the Communist Party of China, this selection was not included in the plan for distribution, but was added temporarily.
This set of Wen 4 stamp designs was based on a portrait of Mao Zedong's side military uniform that was widely circulated at that time, and the stamp name "Wishing Chairman Mao a Long Life without Frontiers" was printed on the bottom edge of each stamp. The original design is 1 set of 4 pieces, the same pattern 4 kinds of brush colors, 4 points, 8 points, 42 points, 52 points face value 4 kinds. Later, the Stamp Issuing Bureau decided to add a 35-cent denomination to a total of 5 stamps. This set of stamps has three characteristics: First, the brush color is changed from different colors to different red tones, and the five denominations are printed with ochre (4 points), big red (8 points), yellow-brown (35 points), zheng red (43 points), and pink (52 points); second, the face value setting has both the commonly used domestic denominations (4 points and 8 points) and the denominations used by international airmail (35 points, 43 points, 52 points).
