The origin of the name Boai County.

Various commemorative postmarks are relatively limited and easy to collect. Only place names are postmarked, because our country has a vast territory and there are many place names. According to the "Post Office Collection" issued by the post office in the 15th year of the Republic of China (1926), there are more than 12,000 post offices of various sizes. According to the recent article on postal services written by Yan Dongkuijun in Volume 1, Issue 8 of this magazine, except for the 20,436 post offices in villages and towns and the 2,047 stamp sales offices, the rest of the post offices , agencies, village mailboxes, etc. have reached about 20,000. It is not easy to collect them all. Moreover, place names in various places are often changed due to changes in the current situation. If there is no reliable reference, it will be difficult. For example, Qinghua Town in Henan is now renamed Boai County; Liba Ji is renamed Minquan County; the rest have new names such as "Freedom" and "Equality".

...In the first issue of the second volume of this journal, Mu Yujun said that the central government used the original Rongyi and Heyin counties in Henan to merge and collectively call it "Guangwu County", etc.
