More realistic immigration [1.6]
MOD creation concept:
In the original game, there is a lack of a concept "people from a poor country immigrate to another country in large numbers because of low living standards". This leads to the fact that even if Japan, which is next door, has a very high living standard, the Han Chinese in China will not be interested in Japan.
In addition, due to various reasons, in the original game, it is very time-consuming and labor-intensive to attract immigrants by improving living standards. Players have to solve the problem of labor shortage by occupying Chinese land and through immigration within the country.
This MOD was born to solve these problems.

MOD Introduction: Every other year, if the living standard of country A is high and there is a country B with a seriously low living standard, then there will be an immigration wave from B to A.
When testing this MOD, without player intervention, in the early stage of the game, the global population will pour into North America, South America, and Australia. In the later stage of the game, the global population will pour into Northern Europe (Norway and Sweden). From current observations, this MOD performs very well.

Detailed introduction to the MOD mechanism: On January 1st of each year, if the living standard of country A is higher than X, and the living standard of country B is lower than Y. And country A opens its borders, and country A has the last three cultural laws, and country A is not an isolationist country. Then trigger an immigration wave from country B to country A.
In 1836-1846, X=10, Y=7
In 1846-1866, X=12, Y=9
After 1866, X=15, Y=12

MOD compatibility:
This MOD runs fully automatically. This MOD does not delete/add game content. So it has good compatibility and should be compatible with most MODs.
MOD创作理念：
原版游戏中，缺少一个概念“一个贫穷国家的人因为生活水平低下大量移民到另外一个国家”。这就导致，哪怕近在隔壁的日本有着很高的生活水平，中国的汉人也不会对日本感兴趣。
此外，由于种种原因，原版游戏中，想要通过提高生活水平吸引移民非常耗时耗力，玩家们不得不通过占领中国的土地，通过国家内移民解决人力短缺的问题。
本MOD为了解决这些问题而诞生。

MOD简介：每隔一年，如果A国家生活水平较高，且存在一个B国家生活水平严重低下，那么发生一次从B到A的移民潮。
测试这个MOD，在没有玩家干预的情况下，游戏前期，全球人口会大量涌入北美洲、南美洲、澳大利亚。在游戏后期，全球人口大量涌入北欧（挪威和瑞典）。就目前的观察来看，这个MOD表现的很好。

MOD机制详细介绍：每年的1月1日，如果A国家生活水平高于X，且B国家生活水平低于Y。且A国家开放边境，且A国家拥有后三项文化法律，且A国家不是孤立主义国家。那么触发一次从B国家到A国家的移民潮。
在1836-1846，X=10，Y=7
在1846-1866，X=12，Y=9
在1866年之后，X=15，Y=12

MOD兼容性：
这个MOD全自动运行。这个MOD没有删减/增加游戏内容。所以它的兼容性很好，应该可以兼容绝大部分MOD。
