战邮1942
On 7 February 1942, in the hardest years of the resistance, the CPC Shandong bureau and the Shandong wartime government established the Shandong Wartime Post General Bureau in Shuangquan Yuzi village, Mashichi township, Yinan county, in the Yimeng mountains — a wartime communications organisation combining intra-party transport, party-newspaper distribution and postal service.
