Amidst the sway of wartime regulations and the vast expanse of geography, an intricate dance of parallel chronicles weaves between Taiwan and Matsu. Within each other, letters ride on transport ships, moistening by the sea breeze, and the emotions brimming within the letters ferment slowly long before they reach shore.

The piece revisits the Military Government era, tracing Matsu's distinctive military postal history, unfurling time-soaked pages, deciphering elusive numerals, and delving into the temporal messages within the Matsu wormhole from 1956 to 1992.
