The main difference between dry method and living method is the different meanings. Mr. kazuo inamori's "living method" made Lao Shu suddenly understand the true meaning of life, and the positive, optimistic and enterprising spirit was integrated into his blood, so that his strong heart could face all the difficulties in life. The "dry method" made the old man understand the meaning of work, corrected his attitude from then on, and treated everything he encountered in his work with full enthusiasm. Then "mental method" is the sublimation of "living method" and "dry method", which solves the problem of mental internal friction from the inner level.
