Internship, as its name implies, is learning while doing. After a period of study, or when the study is coming to an end, we need to know what we have learned or how to apply it to practice. Because any knowledge comes from practice and belongs to practice, it should be put into practice to test learning.

Internships generally include student internships in universities and employee internships in companies. The rigid requirements of enterprises often become a stumbling block for interns to stay and become full members.
