Which countries have good public security and are suitable for immigration?

Culturally speaking, Singapore, Hong Kong and Macao are all places where Chinese gather. There is no cultural difference after immigration, and they can adapt quickly. Institutionally, the United States, Canada, Australia and New Zealand are all countries with advanced systems, with good material foundation, high social freedom, fairness and justice, and great development opportunities, but there are great cultural differences, and the language environment is a problem. Then go to many European countries, where everyone is there, and it is a big society with good social tolerance and inclusiveness!
