My father was just born during the Chinese feudal dynasty was falling apart. The education he received could be both Chinese and Western, with encyclopedic knowledge and sciences. Because he studied hard and always had his own clear life creed, he finished his primary school, middle school and even college in western church schools despite of the influence of feudal family. However, he insisted on studying science and engineering, firmly believed in saving the country by industry. At the same time he did believe neither the feudal superstition nor the western dogmas. Although he lived in a social upheaval time with suffering of several wars, he still kept his life integrity, discipline, willing to teach, eager to help others. He set an excellent example for us.
