This term can also be translated as “nipping the problem in the bud.” Hidden or inconspicuous things are not easily discovered. But there are always warning signs, indications of something newly emerged, slowly developing. All things evolve from hidden to obvious, from small to big, and in time they may lead to harmful consequences. If early steps are not taken to prevent mistakes and problems and to eliminate any defects in time, it will be costly to deal with the consequences, and even disaster may ensue. Thus, people should gain a deep understanding and good grasp of what underlies the evolution of things.
