31 Jul 1943, Chronology of Events Related to Stanley Civilian Internment Camp

Leading Hong Kong surgeon and Nationalist Li Shu-fan begins his escape.  Because of his prominence he was courted by the Japanese and then watched carefully because of his steadfast refusal to co-operate with them. His departure follows a long campaign to convince the authorities that he's given up politics for a life of pleasure so that they'll relax their vigilance and allow him to prepare for and execute his escape.

Dr. Li had sent help to John Fraser and other interned  friends until it became too dangerous to do so. But he continued to take an interest in Stanley:

I used to go down to Stanley Beach, a few hundred yards from the camp, to observe what I could of the inmates. They kept the place orderly, and conducted themselves well. In course of time I noticed that their outdoor games slackened off, no doubt from loss of energy through lack of food.
