How can immigrants move to areas that have been open for a long time?

I haven't immigrated for a long time. The last time I immigrated was at least 3-4 years ago. In the past, when some servers were too hot and there were too many people online, they would emigrate between the two servers, and the immigration adopted the way of registration. Immigration is not allowed now. Dahua's development team has always claimed to be open to free migration (of course, this freedom is also subject to certain constraints), but 1 After many years, it is still difficult to hear its voice but not its "people". This year is enough. For the development team, new information and many changes to be introduced in the future are enough. Let's look forward to the early opening of free immigrants in the future.
