These stamps remind us that Taiwan's population was a lot smaller then, and there was still enough room to have the relatively relaxed "3-3" population policy (urging couples to have their first child only three years after marriage, and to have no more than three children total).
當時台灣人口僅一千多萬，還有空間倡導「三三制」的人口政策（結婚三年生第一個孩子，三個孩子恰恰好）。
