In the 1950s, in order to block broadcasting from the Communists, the government stipulated that every radio user must register with the telecommunication administration for a license. The administration would periodically send an inspector to check. The payment for the license was 10 NTD each season and later changed to 30 NTD each year. Xinju Telecommunication Administration, MTC issued this radio license in 1951 to the Hukou Ammunition Storehouse, Air Force General Supply Office.
