Is Arthur Tien Chin, the hero of China Air Force in World War II, a half-blood?

Arthur Tien Chin's father is a Cantonese and his mother is a white German from Peru. He is going to be regarded as a Sino-German hybrid. This point was recalled by comrades of the National Army, which was not accurate. However, many people who came into contact with Arthur Tien Chin in those years said that his looks, natural military demeanor, passion for fighting and seemingly innate talent were very similar to those of the Germans, and he was proficient in German before going to Germany for training, so he probably did have German descent. In addition, I can't help saying that Arthur Tien Chin is a legendary hero of the air forces of China and the United States, and because he shot down eight Japanese planes on the battlefield in China before the United States participated in World War II, he later officially joined the US Air Force, so he was the first recognized ace pilot in American military history.
