In stark contrast to Qian Yucheng, who took his whole family, young and old, civil and military officials to Kaifeng to become the prince of Taiping, after learning the news that Chen Hongjin led nearly one million people from the Qingyuan army to return to Zhou, Liu Gang, the self-proclaimed emperor of the Southern Han Kingdom, not only did not feel the imminent threat and oppression from the north and northeast of the Later Zhou after the Qingyuan army returned to Zhou, but felt that the two states of Zhang and Quan, which lacked Chen Hongjin and the former Qingyuan army and other civil and military officials, were a piece of fat that he could easily take a bite of. So, I don't know whether it is the arrogance of the long-term man, or the extreme mediocrity, or the so-called "ignorant fearless", just a few days after Chen Hongjin arrived in the capital and was awarded the title of Duke of Qiguo, Liu Gang ordered the generals of Chaozhou, Jingzhou and other areas at the junction with the original Qingyuan Army to lead the army into the territory of Zhangquan and Quan, harassing the localities, arson and plundering.

It's a pity that arrogance and ignorance could not enhance the combat effectiveness of the Southern Han Army, let alone defeat the blocking and counteroffensive of the remaining troops in the Zhang and Quan areas. As a result, the Southern Han army that came to take advantage of the prosperity was defeated and lost by Chen Wenxian and Chen Wenhao, who stayed in the Zhangzhou and Quanquan areas, and fled in panic. Instead of getting any cheap, he lost his troops and lost his generals, and was even chased to the city of Chaozhou by Chen Wenhao and the defenders of Quan. If it weren't for the limited number of troops left behind, he was afraid that he would be taken advantage of by the reinforcements of the Southern Han Dynasty after being entangled for a long time, Chen Wenhao, who led the army to counterattack, would not only show off his might under the city of Chaozhou and leave, but directly attacked the city.

Although the attack of the Southern Han army was a blatant provocation, its attack and harassment ended in failure, stealing chickens and rice, and nothing was gained except the lives of thousands of soldiers. Second, since the combat operation to conquer the Southern Han Dynasty has already begun one after another, and preparations are being made in an orderly manner in all quarters, and it is not appropriate to react strongly to such provocative acts of the Southern Han Dynasty at this time, so as not to prematurely expose one's own intentions and true strength. Therefore, after receiving the joint report of Chen Wenxian and Chen Wenhao, the Later Zhou court did not retaliate immediately, but on the one hand appeased and rewarded the Chen brothers, and on the other hand, ordered all departments to step up preparations to launch an attack on the Southern Han as soon as possible.

Due to the sudden occurrence of Chen Hong's entry into the land and return to the Zhou, the Later Zhou court unexpectedly obtained a coastal area closely connected with the Southern Han Dynasty before the war. Therefore, after taking into account the situation in all aspects, the Crossing Team Committee and the Military Department decided to take advantage of the fact that the operational plan had just begun to be implemented and the relevant combat units had not yet been deployed in place to partially revise the "Guangdong-Guizhou Operational Plan" for the suppression of the Southern Han Dynasty, and to revise the original plan of a feint attack in the north, a main attack in the northeast, and an auxiliary attack on the sea to a plan of a feint attack in the north, an auxiliary attack in the northwest, a main attack at sea, and a direct attack on Panyu, and immediately began to adjust the deployment of various units.

According to the original battle plan, the Later Zhou offensive against the Southern Han would be divided into three directions. Among them, the Northeast Cluster was formed by the Second Synthetic Infantry Division of the "Flying Dragon Army", the 16th and 17th Regiments of the newly formed Sixth Synthetic Infantry Division, the Third Independent Artillery Regiment, the "Langya Battalion" and the "Security Army", and went south along the direction of Xiongzhou, Shaozhou, and Yingzhou to attack Panyu;

The 3rd Regiment of the 1st Synthetic Infantry Division, the 15th Regiment of the 5th Synthetic Infantry Division, the 18th Regiment of the 6th Synthetic Infantry Division, the Divisional Artillery Regiment, the Cavalry Regiment, and the six regiments of the "Security Army" formed a northern cluster, avoiding the dangerous roads of Wuling (Yuecheng Ridge, Du Pang Ridge, Mengzhu Ridge, Qitian Ridge, and Da Geng Ridge), marching to Hezhou, making a false impression of attacking Panyu from this direction, and attracting the Southern Han Army to the north for reinforcements. The first is to stabilize the western line and ensure the safety of the flank of the Northeast Cluster. Second, it was also to mobilize the Southern Han army out of Panyu, not only to alleviate the obstacles of the northeast cluster siege, but also to create conditions for the annihilation of the Southern Han heavy army group in the movement;

With the "Flying Dragon Army" Navy Southern Expedition Task Force, the first battalion of the first regiment of the Marine Corps, the newly formed second regiment, and the newly formed naval special forces "Heijiao Battalion" as maritime clusters, they harassed the coastal areas of the Southern Han Dynasty, and landed near the left side of Panyu when the time was right, and cooperated with the northeast cluster to attack Xingwangfu.

The reason why the sea cluster that can directly attack Panyu was not taken as the main direction of attack when the plan was formulated was mainly due to the fact that the nearest port to Panyu that was directly controlled by the Later Zhou Dynasty was far away from the mouth of the Yangtze River, and even if Wu Yueguo was willing to provide logistical support for the Zhou army, Fuzhou, which was suitable for logistics support port, was also thousands of miles away from Panyu, and the transportation capacity of the "Flying Dragon Army" naval transport, auxiliary ships and civilian ships suitable for long-distance maritime transportation that the imperial court could collect. At such a distance, there is a limit to the number of men and horses that can be supported by relying solely on supplies from the sea. Therefore, for the crossing team that has never fought uncertain battles, when there are other methods available, they usually will not choose this kind of plan with more storage and no certainty.

Now, with the former Qing Yuan Army, which is adjacent to the Southern Han Dynasty and has many ports and coastal islands, not only has the supply distance at sea been reduced by more than half compared with before, the supplies that the same ship can carry in the same time have more than doubled, and the probability of danger during the voyage has also been reduced by more than half. And, as the transport distances have been shortened, there is a place for vessels that were previously excluded. In this case, it is reasonable to adjust the corresponding combat plan.

First of all, the maritime cluster consisting of 80 warships, more than 200 transport and auxiliary vessels, and more than one regiment of the Marine Corps of the "Flying Dragon Army," which was originally only responsible for auxiliary attacks, has been expanded, and the number of warships has been increased to 120 and the number of transport and auxiliary vessels has increased to nearly 800, so as to ensure that all the troops, horses, and logistical materials of the two regiments of the "Flying Dragon Army" Marine Corps, the Second Composite Infantry Division, the Second Independent Artillery Regiment, and the "Black Jiao Battalion" can be transported to the water near the mouth of the Pearl River at one time. And cover the marines and army units to land near the left of Panyu and attack Xingwangfu directly.

Second, the Northeast Cluster, which was originally the main attack, was reduced, and the 2nd Composite Infantry Division, which was originally attached to the cluster, was transferred to the sea to participate in the operations of the maritime cluster, while the rest of the troops continued to attack according to the previously established advance route. However, the offensive was no longer aimed at capturing Panyu, but instead attracted the main force of the Southern Han Army to the north, and chose the opportunity to cooperate with the Northern Cluster to encircle and annihilate the heavy army group of the Southern Han Army.

As for the Northern Cluster, since its role and operational objectives have not changed, the original organization and battle plan will still be maintained.

Due to the need to readjust the deployment and mobilize the troops and horses, the relevant preparations for the pacification of the Southern Han Dynasty were increased compared with the previous plan, and it was not until the 15th day of the second lunar calendar of the sixth year of Jianlong that the preparations were ready, and the troops and horses participating in the operation were deployed in place.

On February 20 of the lunar calendar in the sixth year of Jianlong, the Later Zhou court issued an edict to conquer the emperor in the name of Liu Gang's arrogance of the emperor, great rebellion, and cruelty to the people, and appointed Tang Chao as the commander of the camp capital in the south and the commander of the Northeast Route Army (commander-in-chief of the Southern Expeditionary Army and the commander-in-chief of the Northeast Cluster), and the commander-in-chief of the expedition; Yang Xin was appointed as the deputy commander of the southern camp and the commander of the Northern Route Army (deputy commander-in-chief of the Southern Expeditionary Army and commander-in-chief of the Northern Cluster); Huang Hai was appointed as the deputy commander of the southern camp, the commander of the southern route army, and the commander of the naval army (deputy commander-in-chief of the Southern Expeditionary Army, commander-in-chief of the maritime cluster, and commander-in-chief of the naval task force), and led 100,000 land and water troops to the south from now on.
