Joseph / Yuk-cheung TSANG / CHANG (aka BAAG No. 63) [????- ]

No. 63 should be Joseph Tsang Yuk-cheung.  He was very active with respect to making contacts with the Stanley Internment Camp, the HKU professors, the doctors, the bankers, as well as the Indians. He had a brother or cousin working in Stanley Camp and was thus able to gain a degree of access. After the Ansari incident, he returned to AHQ and was reluctant to continue service.  He was referred to study at the HKU in Free China under Prof. Gordon King. It was said that he was a teacher at Lasalle College before the war.  I'm a bit surprised by the report that said he could not speak English though.
