As the troops of the 47th Group Army began to enter the battlefield in Guangxi, Sun Weiguo had begun to directly command the troops of the Third Cavalry Army, the New Seventh Army, the Provisional Ninth Army, and the 46th Army, while the three armies of Sun Weiguo's 47th Group Army were under the jurisdiction of the Honorary Third Division, the Honorary Seventh Division, the Provisional Fifth Division, the Provisional Sixth Division, the Honorary Fourth Division, the New 11th Division, the Security Division, the 201st Division, the First Cavalry Division, the Second Cavalry Division, and the Artillery Division, and these troops totaled more than 100,000 people.

When the troops of the New Seventh Army and the Provisional Ninth Army rushed to Guangxi to fight, Sun Weiguo immediately began a full-scale counteroffensive against the Japanese army.

The troops of the 47th Army were undoubtedly formidable, and under their counterattack, the Japanese troops began to retreat one after another, and finally the commander of the 22nd Army, Hashimoto Group, had to issue an order to assemble all the Japanese troops in Qinzhou, where the army headquarters was located.

On December 25, 1939, the remnants of the Japanese 16th Division, 18th Division, 57th Division, Guards Division, Indochina Dispatch Army, Heavy Artillery Ninth Brigade, Independent Tank First Brigade, Independent Tank Second Brigade and other remnants began to set up defensive positions in Qinzhou, while Sun Weiguo ordered the New Seventh Army, the Temporary Ninth Army, the Third Cavalry Army, and the 46th Army to begin a fierce attack on Qinzhou.

The two sides fought fiercely in Qinzhou, and after more than ten days of fierce fighting, the troops of the 47th Group Army annihilated all the Japanese troops in Qinzhou.

However, after this operation, the troops of the 47th Group Army also suffered heavy losses, and although the 11 divisions of the three armies annihilated more than 100,000 Japanese troops, they also suffered more than 30,000 casualties.

With the main force of the Japanese 22nd Army being completely annihilated in Qinzhou, the 47th Group Army did not have time to rest and recuperate, and then immediately plunged into the operation again.

The troops of the 47th Group Army, under the leadership of Sun Weiguo, began to go to Nanning and launched an attack on the Japanese Fifth Division.

By the beginning of February 1940, the 5th Division of the Japanese Army in Guangxi was completely annihilated by the troops of the 4th Theater, which was the greatest victory on the battlefield.

The Central Military Commission was naturally very satisfied with the successive successions of the troops of the 47 th Group Army, but by now the units of the 47 th Group Army had suffered more than 50,000 casualties, and all of its main forces had reached the point of being wounded and weakened.

At the same time, Sun Weiguo began to be promoted to the rank of second-class general of the army, and the troops of the 47th Group Army were also expanded to four army numbers.

At this time, the 47th Group Army began to be transferred to Yunnan for rest and recuperation, and at this time, the 47th Group Army began to have four corps under its jurisdiction: the New Seventh Army, the Provisional Ninth Army, the Third Cavalry Army, and the Reserve Sixth Army, with a total strength of more than 150,000 troops.

Time passed in a hurry, and in the blink of an eye, it was the end of 41 years, and during this period of time, the troops of the 47th Group Army did not receive any combat missions.

However, during this period of rest and recuperation, the troops of the 47th Group Army received assistance from the US military, and a large amount of supplies began to be transported to the garrison of the 47th Group Army in Yunnan.

"Commander-in-Chief, we have just received an order to form an expeditionary force with the troops of the Fifth, Sixth, and 66th Armies, and we are about to go to Burma to assist the British army in defense."

Somewhere in Yunnan, in the headquarters of the 47th Group Army, Chief of Staff Zhao Lerong came to Sun Weiguo, he saluted Sun Weiguo, and then handed him the telegram.

Sun Weiguo took the telegram and looked at it, his face showed a calm expression, when the troops of the 47th Group Army began to be stationed in Yunnan for a long time, Sun Weiguo expected this.

Now seeing the content of the message, Sun Weiguo is not surprised at all.

"Order the troops to be ready and all to combat readiness." Sun Weiguo began to give orders to the troops.

Although the 47th Army, together with the 5th, 6th, and 66th armies, formed an expeditionary force to enter Burma to assist the British in the war, it was not until March 1942 that the troops of the 47th Army entered Burma to fight.

On the battlefield in Burma, although the British army continued to interfere with the command, the troops under the command of Sun Weiguo still brought a devastating blow to the Japanese army.

Until the end of 1942, on the battlefield in Burma, the expeditionary force units were completely dominant, and in 1943, the troops of the 47th Group Army began to be transferred back to China to participate in the war.

Subsequently, under the leadership of Sun Weiguo, the headquarters of the 47th Group Army successively participated in the Battle of Western Hubei and the Battle of Changde, until the victory of the Anti-Japanese War.
