During the period of the Republic of China, Li Zongren's Guangxi troops were very effective, especially the Seventh Army of Gui Jun, which was known as the "Iron Corps". The Seventh Army hardly suffered defeat in the Northern Expedition and the warlord melee.

In the Guangxi-Tang War, hundreds of thousands of Xiang troops, famous for their toughness, were defeated by tens of thousands of people and merged.

At the beginning of the Central Plains War, when faced with less than 30,000 troops,10,000 Xiang Army suffered another fiasco.

After the Central Plains War, Gui Jun retreated to Guangxi, and the Xiang, Dian and Yue armies assembled nearly 6.5438+200,000 troops in an attempt to defeat Gui Jun and occupy Guangxi. However, Gui Jun's more than 20,000 troops were divided into two ways. The 6.5438+100,000 troops defeated more than 30,000 Yunnan troops all the way, and then defeated nearly 30,000 Guangdong troops, driving them out of Guangxi. On the other hand, 65,438+/kloc-0,000 people defeated nearly 60,000 Xiang troops in Guilin.

During the period of War of Resistance against Japanese Aggression, the Japanese spoke highly of Gui Jun and Gui's militia, and Gui Jun's performance was also considered by domestic historians as "the trump card of the miscellaneous army" and "the fighting capacity can be comparable to the most elite troops of the Central Army" and so on.
