In the year and a half after the end of the Argentine War, the local population continued to show a rapid growth trend, with more than 800,000 newborn babies, and with the successive migration of immigrants from overseas, the native population of Han reached 9 million at the beginning of 1881.

Among the newly born babies, the number of mixed-race babies has increased more than four times compared with before the occupation of Argentina, and among the 800,000 newborn babies, about 140,000 mixed-race babies, more than 80 percent of these babies are white women who choose to stay in Argentina, Uruguay and other places to marry Chinese men, and the remaining part of the babies are children born to Chinese and Indian mixed-race children.

After the Chinese became the masters of Argentina, Uruguay and other regions, the white people left behind either chose to abandon the homes and property they had lived in for generations, and chose the United States, Canada, Colombia and other countries where white people dominated, or they could only accept the intermarriage decree issued by the Han government and choose to form a new family with Chinese immigrants.

As for the third way, returning to their hometown in Europe is only suitable for the aristocracy, big businessmen, and large landlord class who have some huge assets, and they can use their financial resources and connections to return to Europe to start a new life, but for the descendants of white immigrants who have lived in South America for hundreds of years, Europe is just a cultural symbol that affects their living habits, even if they are willing to return there, but the population of European countries is growing too fast, and they are rushing to settle surplus population in overseas colonies. It is simply impossible to accept ordinary white immigrants with no skills.

The road back to his hometown in Europe was blocked, and abandoning his family business and immigrating to the United States, Canada and other countries was not the best choice, so after the war in the La Plata area, Argentina and Uruguay, out of a total of more than 1.8 million whites, only nearly 200,000 finally chose to leave their homeland, accounting for about one-ninth of the total number of local whites.

Staying in the local area means learning to integrate into the mainstream Chinese society, and gradually moving closer to the Chinese in terms of culture and living habits, but fortunately, the Han government considered the huge hidden dangers that may be brought about by blindly forcing white people to integrate into Chinese society, so while acknowledging and respecting white people's living habits, it also issued a series of decrees to give white residents who have obtained formal national status the same rights as Chinese, they can own their own land, and white children can go to public schools like Chinese children, which is compulsory for five years.

Compulsory education and military service are the rights of every Han national, and they are also the obligations they must fulfill, so when they accept the government's non-discriminatory treatment, they must also go to local schools and military service institutions to enroll and register on time, and if there is any act of resistance, they will be punished and punished by the grassroots government.

After the full implementation of the integration policy of combining punishment and reward, more and more white Argentines and Uruguays have gradually adapted and accustomed to the integration of Chinese people from the initial covert resistance, to the gradual adaptation and habitual adjustment, and finally to let go of their prejudices, and are willing to marry the Chinese members of their families.

White and Indian women who married Chinese, as well as the children they gave birth to, were branded as Chinese, even though they had white skin.

As a result, the number of people classified as Chinese in the government's census data exceeded 7.5 million, while the number of whites and Indians on paper fell to 1.6 million.

Chinese, mixed-race, white, and Indian children are educated in the same school, and when they return home after school, they will also play the game of riding alpacas and catching alpacas with children of different colors who live together.

In the more than 600,000 square kilometers of the Pampas, one of the most fertile black soils in the world, you can often hear the laughter of children in the settlements.

There is no scorching heat in summer, no severe cold in winter, the pastures are lush, the climate is humid, the rainfall is abundant, and the suitable natural environment provides the necessary material basis for the integration of different races, and on the endless grassland, the grass is full of grass, and at the same time grows more than 80% of the local cattle, sheep and livestock, the cattle herd on the Pampas grassland, mainly Angus cattle, Angus cattle are small in size, tight in meat quality, have the advantages of high survival rate, easy to breed on a large scale, thick and large pieces of Angus beef not only enrich the table food of the local people, At the same time, it also brought considerable profits to the people who settled on the grassland.

The vast Pampas grassland accommodated many immigrants and livestock, and in the vast territory of the Han Kingdom, various regions with different natural environments also explored the most suitable development routes according to their own conditions.

Wuzhou (Uruguay), Yangzhou (Rio Grande do Sul), Luozhou (Santa Catarina) and other Jiangdong prefectures, relying on the local large coal production area and the political status of the land of Longxing of the Han State, vigorously developed the heavy industry and light industry system, making it the most important industrial center of the Han State, and the local animal husbandry development is second only to Songzhou (Buenos Aires).

Located in the high altitude of the eastern Andes Mountains, the former province of Salta is barren with scarce precipitation and extremely high temperature differences.

According to the local climate characteristics, the local government according to the central government's national development plan, according to local conditions to develop wine planting, has introduced Malbec grapes from France and transplanted more than 20 kinds of South American white grapes, after a period of development, the local wine planting industry, began to show good economic benefits.

In the northern part of the Han Kingdom, the Gran Chaco Plain, which also belongs to the Rio de la Plata Plain, is densely forested and fertile, and the relatively hot climatic conditions provide conditions for the growth of rubber, cocoa and other cash crops.

The development of the northern, northwestern, central, and eastern regions has gradually entered the right track, while the southern Patagonian wilderness has also developed from scratch in accordance with the three major industrial goals of mineral exploitation, animal husbandry and breeding, and marine fishery product fishing.
