After marrying, Wu opened Tsanshan, a shop specializing in Buddhist paraphernalia, in Taipei's Shuanglien district in 1976. Two years later the shop saw a chance visit by Han Pao-te, then dean of the College of Science and Engineering at National Chung Hsing University, now head of the Museum of World Religions.
成家後，一九七六年吳榮賜在台北雙連開設「讚山佛具店」；一九七八年，時任中興大學理工學院院長、現任世界宗教博物館館長的漢寶德，無意中經過吳榮賜所開的店面，看到他正操刀為佛修面。
