1936年10月，经过总计两年的艰苦转战，红军三大主力在甘肃会宁、将台堡地区实现了大会师。它标志着中国工农红军长征的最后胜利，也进而促成了西北局面的大变化。值此长征胜利六十周年之际，谨撰文以志纪念，并就三大主力会师的背景、经过及其对西北局面的影响作些考察和探讨? In October 1936, after a total of two years of hard fought fights, the three main forces of the Red Army in Huining, Gansu Province, realized the assembly division in the Taibao area. It marked the final victory of the Long March for the Red Army of Chinese Workers and Peasants and contributed to the major changes in the situation in the northwest. On the occasion of the 60th anniversary of the victory of the Long March, I would like to write an article dedicated to commemoration and to make some observations and discussions on the background of the three main principals and their impact on the situation in the northwest.
