Reading is not the only way to gain knowledge of the work in the past. There is another large reservoir (知识库) which may be called experience, and the college student will find that every craftsman (工匠) has something he can teach and will generally teach gladly to any college student who does not look down upon them.

Another source of knowledge is the vast store of traditional (传统的) practices handed down from father to son, or
A. we’ll invite the craftsman to teach in the college
B. schools and books are not the only way to knowledge
C. scientific discoveries late based on personal experience
D. discoveries and rediscoveries are the most important source of knowledge for a college student
