Both in the revolutionary war years and in the period of peace building, the Party and the government attach great importance to the exchanges between China soldiers. During the period of War of Resistance against Japanese Aggression, most local governments designed and issued military mailing envelopes for "supporting the army and resisting the enemy". For example, during the period of 1942- 1945, the government of Shandong Jiaodong anti-Japanese base area specially produced a batch of envelopes to support the army and approved the military region to specially produce envelopes to commemorate Ren Changlun, and launched the month of supporting the army in March of 1945, and all the mails sent to anti-Japanese soldiers were delivered free of charge. The government of Jiaodong anti-Japanese base area stipulates that free envelopes supporting the army are sent to the military region (referring to Jiaodong military region) and divisions by Jiaodong wartime postal administration, and then sent to the military region and divisions respectively according to the serial number of the army; Anyone who sends cash or registered mail with this envelope will go through the registration formalities free of charge; When forwarding or delivering an envelope, the post office system regards it as a registered letter and must deliver it to the recipient in person.

During the period of 1952- 1953, the logistics department of Chinese people's Volunteer Army printed a set of (6) envelopes mailed by volunteers and distributed them to volunteers for internal use. The mailing seal is16cm long and12.5cm wide. When in use, write the contents of the letter on the back of the mailing envelope, fold it along the dotted line and paste it firmly, which is very quick and simple to meet the needs of the battlefield. The right half of the front of the mailing envelope is printed with heroic propaganda pictures of volunteer soldiers and pictures reflecting China's construction achievements; Slogans such as "Long live Chinese people's Volunteer Army" are printed on the back, and sanitary tips for marching operations, such as how to rescue the wounded and how to purify drinking water, are also printed in the upper and lower blanks.

On 200 1 August1day, the State Post Bureau officially issued postage postcards to the army for the first time. This postcard is specially designed by Yang Guchang, a famous military art designer and designer of Red Army Post. 1 set of 4 stamps are entitled "Army, Navy, Air Force and Armed Police" respectively. Postcards issued by the state since the founding of the People's Republic of China include ordinary stamps, commemorative stamps (JP), special stamps (TP) and scenic stamps (FP). The first issue of commemorative postage film for servicemen (JP for servicemen) has become a new variety of stamp products in China, which is very precious because of its small circulation.
