--------------------------------------------------------------------------------------------
This set of 2021 stamps was designed by Du Yukai, and the pictures continue the characteristics of the previous two sets of this series, using modern hand-painted illustrations. The colors are bright and lively, and the pictures are fresh and natural.
The first stamp mainly shows the working scene of the first unmanned lunar surface sampling by the "Chang'e 5" lunar probe, which is the final battle of the third phase of China's lunar exploration project;
The "Struggle" full-sea deep manned submersible shown in the second stamp is my country’s first important equipment with the ability to enter global seas. It is also the world’s largest manned submersible of the same type and has the largest number of crews in the world. The equipment with the longest time and the strongest operational capability;
The third stamp "Revealing the mystery of locust swarms and disasters" shows that the compound 4-vinyl anisole (4VA) is an important entomological research on the pheromone of migratory locust swarms through scenes such as locust gathering and 4VA chemical formula. A breakthrough, this research makes possible the green and sustainable prevention and control of locusts;
The fourth stamp features "Hualong No. 1" as the main picture, supplemented by energy formulas, nuclear fission and other element symbols, showing my country’s third-generation pressurized water reactor nuclear power innovation achievements with completely independent intellectual property rights. This achievement marks my country’s The technological level and comprehensive strength of nuclear power have ranked first in the world;
The fifth stamp uses the contrast between ancient and modern, DNA strands, ancient strata, etc., to show the theme of the picture "Ancient DNA reveals the migration dynamics and ethnic origins of Chinese prehistoric people". This result fills in important information about the genetics, evolution, and adaptation of prehistoric humans in the East, especially in China.
This set of stamps was printed by Henan Posts and Telecommunications Technology Co., Ltd. with offset printing, supplemented by hot stamping, full-color printing and magnetochromic processes. While demonstrating the technological sense of stamps, it also adds fun, ornamental and interactivity.
For the first stamp, the magnetochromic process was applied to the stamps for the first time. With the help of magnetic objects, mysterious patterns in the distant space can be observed. Under the ultraviolet light, the lunar surface environment and the marvelous picture of the moon probe lifting off can be viewed as if on the spot.
The second stamp uses a cold stamping process to three-dimensionally present the metallic texture of the Struggle submersible, and the full-color printing process under the ultraviolet light reproduces the scene of its 10,000-meter dive.
The third stamp uses a cold stamping process to show the chemical molecular formula and other elements. The special process highlights the touch of the locusts. The full-color printing process makes the picture more vivid under ultraviolet light.
The fourth stamp uses the cold stamping process and colorless fluorescent blue to simulate the nuclear reaction process, highlighting the advanced nature and safety and reliability of Hualong One.
The cold stamping process allows the fifth stamp to appreciate the infinitely extending double helix structure from the side light, showing the dynamics of crowd migration. Under the ultraviolet light, the green double helix structure is richer and more three-dimensional.
