NARA上一个档案:“CHAO MU-A typical portrait of "Chao Mu" (grandmother) of the Chinese farm land who tills the soil with primitive tools alongside the bases and modern mechanical equipment of Major General Claire Chennault's 14th Air force in the fight (U.S. Air Force Number 56118AC)”,ID=204831520,只有一张图,和一页说明。说明就是题目。Chao Mu估计是赵母。
