In February 1881, the Chinese population in the Samoan Islands reached 14,000, and the Chinese replaced the indigenous Polynesian people as the largest ethnic group in the region.

In March 1881, more than 200 militia troops stationed on Tutui Island to take over control of the island, and then the American merchants on the island were forced to agree to the conditions put forward by the Han government, and at the price of 190,000 silver dollars, they would package their land and property to the Han side, and they would completely withdraw from the Samoan Islands after the transaction was completed, and return to the mainland of the United States with their Polynesian servants.

After squeezing American businessmen out of the Samoa Islands and cutting off the possibility that the United States would take businessmen as the forerunner and fight for the ownership of the Samoan Islands, the Han government officially included the Samoa Islands into the territory of the mainland, and together with Easter Island and Zilu Island, they were jointly named the Yizhou Islands, and their political status was temporarily demarcated as the Zhengcheng city, and the administrative capital was set up in Apia, in the Samoan Islands, and the governor of the Yizhou Islands and the South Pacific Squadron designated by the central government to jointly manage local affairs.

The South Pacific Squadron is a newly established fleet, and its warship composition includes two self-built 1,350-ton light cruisers, four medium-sized armed merchant ships, and five steam transformation ships for transportation and supply tasks.

At the beginning of January 1881, the central government made further adjustments to the establishment of the navy, and the Second Fleet was stationed in Haizhou, with Haizhou Yishui Port (Port Montt) as its home port, renamed the Pacific Fleet, and the First Fleet was renamed the Atlantic Fleet.

After the completion of the adjustment of the new establishment of the Navy, two newly built 1,350-ton light cruisers were delivered to the Pacific Fleet, and then on the basis of the two light cruisers, the South Pacific Squadron, a second-class detachment subordinate to the Pacific Fleet, was established.

Both the South Pacific Fleet and the Caribbean Fleet have a certain degree of autonomy, but because of the geographical location, the Caribbean Fleet is weak, and only a few gunboats with a displacement of 500 tons support the situation, and the Tolti Island occupied by the Caribbean Fleet still belongs to Haiti on the surface, and the island area is only small, and the area of only 180 square kilometers does not allow the daily docking and maintenance of large and medium-sized ironclad ships. The South Pacific Fleet is the third largest maritime force in the mainland after the Atlantic Fleet and the Pacific Fleet.

The South Pacific Fleet shoulders the heavy responsibility of maintaining the safety of the Pacific migration routes, distributed in the Samoa Islands, Zilu, Easter Island, a total of 500 naval crews, 400 Marine Corps troops, 1,000 militia reserve forces, all under the unified command of the South Pacific Fleet, considering the importance of the South Pacific Fleet, the Navy General Staff raised the level of the South Pacific Fleet to the deputy division fleet, and the captain of the fleet and the candidate for the governor of Yizhou are temporarily concurrently served by the commander of the Marine Corps, Feng Guoan.

In March 1881, two months after Feng Guoan took over the duties of Governor of the Yizhou Islands and the South Pacific Fleet, in order to cope with the impending wave of immigration, he began to recruit Chinese immigrants to work on the expansion of the port of Apia.

The port of Apia is located on the island of Upolu in the Samoan archipelago.

The coastline of the port is 694m long and the maximum water depth is 12m. According to the specified construction requirements, after the completion of a round of construction period, the expanded port can have the capacity to carry and supply 20,000 migrants at a time.

In April 1881, the construction of the Samoan Islands was in full swing, and in the coastal areas of the Far East mainland, the ban on overseas immigration issued by the Qing government finally failed under the strong desire of the people to survive and the urging of the Western powers.

More than a year after the ban was in place, groups of refugees who had gone to sea to survive were expelled by the Qing government and cut off from the migrant ports.

On the seventh or eighth day of the lunar month, the army of refugees gathered in the northern coastal areas was hungry and cold, and hundreds of thousands of people froze to death in the cold wind every day.

Experiencing the threat of death, in the face of cold and hunger,

The last shred of humanity and dignity of the refugees is not worth a bowl of life, the Manchu government promulgated the ban on immigration, is to destroy the hope of the refugees to live, under the extreme despair, the expelled refugees burst out of the long-accumulated strength, batch after batch of young refugees gathered, under the command of a small number of people, launched a riot, and constantly attacked the county and villages under the rule of the Manchu government.

In the more than a year since the immigration ban was implemented, the number of refugees involved in the riots exceeded 100,000, and the output of the local gentry and Western foreigners in the coastal areas was all affected by the riot refugees, and the economic losses suffered by the local gentry alone were an astonishing figure.

At the same time, some Western countries, whose economic interests had been damaged, threatened the Manchu government with force to resolve the refugee riots and restore economic order in the coastal areas.

Feeling once again the destructive power of the refugee uprising,

The Manchu government could only swallow the bitter fruit, while appeasing the Western countries and promising to compensate them, while threatening the refugees with a fierce internal threat that they would not defect to the Han State and rebel, otherwise they would be dealt with as treason.

The Manchu government's self-deceptive threats were probably not believed even by themselves, let alone the local Han gentry and refugees who were bent on survival.

After the abolition of the immigration ban, a huge wave of immigrants to the sea reappeared, and because of the weakness of the Manchu government in the face of the threat of Western countries, more people saw through the nature of the Manchu government's strong and middle-class cadres, and in disappointment, they also went to sea to join the Han country with the refugees who fled the famine.

The northern provinces of Quang Ninh and Lang Son were the main migration bases of the Han in the Far East, and refugees from Liangguang and southern Fujian generally stayed in the northern provinces of Annam for a period of time, and then went to the Han mainland by boat in batches.

However, with the intensification of the French colonialists' aggressive activities in the Annam region, the status of the two northern provinces of Annam as a base for immigrants is becoming more and more powerful, and the contradictions and conflicts between the Nanyang Corps stationed in the two northern provinces and the French colonizers are becoming more and more intense.
