The difference between a personal work and a collection of works was that a personal work was usually the author's exploration and attempt on his own creative path, while a collection of works was a collection of works that the author had obtained a certain degree of recognition and achievement. Under normal circumstances, the number of personal works may be relatively small and they may focus more on exploring and trying new creative directions and styles. On the other hand, the collection focused more on the author's achievements and recognition, including the number, type, style, quality, and other aspects of the work. Individual works usually focused more on the author's creativity and imagination, while collections focused more on the author's creative skills and performance. At the same time, the collection may also include some representative works that have been recognized. These works may have an important impact on the author's creation. Generally speaking, personal works and collections are important achievements of the author's creation. They not only reflect the author's creative ability and level, but also provide readers with a more comprehensive and in-depth understanding.
