The 20th century was a time of incredible change in China.My generation felt lucky and blessed to be born in the 20th century, survive its vicissitudes, and witness the transformation of the country. Poverty-stricken in our youth, we were fortunate to become workers, fighters, and crafters of the development of science and technology in China, and be granted the opportunity to share in making the changes happen. Most of my contemporaries saw the success and failure, windstorms and tempests, suffering and tears, and ultimately the rejoicing and jubilation that we experienced, as being all part of life in the great era. That experience should be preserved for generations to come, and for historians interested in Chinese studies.
