Immediately after defeating the French at the Battle of Fisherman's Wharf, 孫開華提督General Sun Kai-Hua had taken ill from drinking too fast and too much cold tea back at the camp. After much search, a young physician of Bac-dau-a by the name of 鄭木筆 was invited to treat Gen Sun and Sun was in fact quickly cured. Dr 鄭, affectionately addressed by his patients as 木筆先 (Vo' Bi' Sen), subsequently became a most renowned doctor of northern Taiwan.
A mere 10 years after the Sino-French war, in 1895, China ceded Taiwan to Japan's colonial rule. Following the lesson learned from the French, the Japanese invading force landed near Keelung, not Danshui. Gen Sun孫開華, however, did not live long enough to see this happen having already passed away in 1893. The Japanese rule was to last until Aug 14, 1945. This occupation proved costly to the 鄭Cheng family. A member of the next generation, 鄭子昌醫師 (EyeDoc's father), together with 341 other Taiwanese physicians, medics, and medical assistants were drafted and sent to serve in the Pacific War; 247, including the young Dr 鄭, perished in French Indochina on Jan 12, 1945 (see here for details).
