1921年外蒙古“二次独立”事件中,外蒙古的大量内地商民沦为难民并纷纷逃离,其中库伦和恰克图的大部分难民进入俄国境内,最终被中国政府和东北当局接运回国。对于库恰难民的数量,各种文献中记载不一,结合当时实际以及对文献记载的考证,库恰难民人数应在5万左右。 In the incident of “second independence” in Outer Mongolia in 1921, a large number of merchants from the Mainland in Inner Mongolia became refugees and fled in succession. Most of the refugees in Coulomb and Chaktu entered the territory of Russia and were eventually taken over by the Chinese government and the Northeast authorities Shipped back to China. For the number of refugees in Kucha and their different records, the number of refugees in Kucha should be around 50,000 in light of the actual conditions at that time and the research on the literature.
