Lin's father was good friends with the people at the management office, and the "Dengshan Shi Tang" restaurant that he ran happened to be right next to the Fenqihu train station. Thanks to his personal connections and geographical serendipity, in 1955 he was able to go into the business of providing railroad biandangs.
由於林金坤的父親與管理處人員熟識，經營的「登山食堂」也正好在奮起湖車站旁邊，人和加上地利之便，就這麼經營起鐵路便當的生意。
