In the period of late Qing Dynasty and early Republic of China, Chinese society transformed increasingly rapidly from traditional to modern which accompanied with more and more evident changes. On the one hand, newfashioned school education developed rapidly; on the other hand, social occupational structure underwent significant changes. Thus vocational guidance gradually became necessary to social development. Zhou Yi-chun launched a series of activities such as vocational speeches at Tsinghua School in 1916, which was viewed as the beginning of organized modern Chinese vocational guidance.

清末民初，中国社会由传统向近代转型的速度日益加快、变化日益明显，一方面新式的学校教育日益发展，一方面社会职业结构也发生了显著变化，职业指导逐渐成为社会发展的需要。1916年周诒春在清华学校开展的职业演讲等活动，被看作是近代中国有组织职业指导活动的开始。
