五四时期,胡适发动白话文改革并挑起“问题与主义”之争,在当时产生了巨大影响,但直至今天这两件事仍颇受争议。正确认识这两项运动对于指导今天的文化、政治仍大有裨益。 During the May 4th Movement, Hu Shih launched the vernacular reform and provoked a “problem-and-doctrine” controversy that had a huge impact at that time. However, these two issues are still controversial until now. Correct understanding of these two campaigns will still be of great help to guide the culture and politics of today.
