Why did the Sichuan Army not leave the Guangdong Army?

The original words of this sentence are "Before the Sichuan Army left, the Guangdong Army was exhausted", which is used to describe that during the period of China and War of Resistance against Japanese Aggression, the Guangdong Army made great sacrifices to support War of Resistance against Japanese Aggression, while the Sichuan Army in Sichuan Province failed to leave Sichuan in time for various reasons, which led to Guangdong Province becoming the front line of China's anti-Japanese war.

Guangdong province is a province in the south of China, and its geographical position is very important, which is the frontier position of China's resistance to Japanese aggression. In War of Resistance against Japanese Aggression, Guangdong Province has become one of the important battlefields in War of Resistance against Japanese Aggression, China. Due to the terrain and other reasons in Guangdong Province, the troops in Guangdong Province faced great difficulties in fighting against the Japanese aggressors, but they were brave and good at fighting and made great contributions to War of Resistance against Japanese Aggression, China.

Sichuan Army refers to the army from Sichuan Province, which was once regarded as the backbone of China's anti-Japanese war because of its relative stability and abundant resources in the early days of War of Resistance against Japanese Aggression. However, after the full-scale anti-Japanese war broke out in 1937, the Sichuan army did not leave Sichuan in time for the anti-Japanese war, but did not leave Sichuan until 1939, which made Guangdong Province the front line of China's anti-Japanese war.

Therefore, this sentence is a tribute to the great contribution and sacrifice made by Guangdong's Guangdong Army in War of Resistance against Japanese Aggression, and it also expresses the dissatisfaction and criticism of Sichuan Army's failure to leave Sichuan in time.
