When Hitler described his childhood in Vienna in his autobiography, he mentioned that he was selflessly helped by an Austrian China family when he was poor. This family named Zhang (pronounced "CHEUNG" in German and translated as "Cheng" in English) once gave him 500 Austrian schillings for tuition and living expenses. He is often invited to stay at home for dinner. When he learned that Hitler had a great talent for painting, the kind China family also took the initiative to help him contact the famous Vienna University, hoping to help him enter the university. "Their help is selfless and unforgettable ..." Hitler once sighed when talking about his past. Later, Hitler took power and merged with Austria, but at that time, no matter what method was used, this kind benefactor was never found again.
