What is the reason for the fifth move of Northeast Old Aviation School?

The fifth move of Northeast Old Aviation School was in June 1946 1 1. The Kuomintang reactionaries once again launched a large-scale attack on the Northeast Liberated Area. The plane of the Kuomintang Air Force followed Mudanjiang for bombing and strafing, and the aviation school was forced to move from Mudanjiang to Dong 'an on the Xingkai Lake in Heilongjiang. At this time, it has reached the severe winter season, with heavy snow all over the sky. The temperature is MINUS 30 to 40 degrees Celsius. When your hand touches the iron, it will peel off a layer of skin. After more than a month's rush to repair the airport, the Aviation School finally settled in Dongan at the end of 1 1. In a year's time, it is undoubtedly a miracle that our Northeast Aviation Organization can survive and develop without being attacked by the Kuomintang air force.
