Why did I leave my beloved land and choose to immigrate to Portugal?

At present, the domestic economy is developing rapidly, but it inevitably brings serious pollution, which is also an inevitable consequence of the economic development process. Any country must go through a stage of prosperity and rejuvenation. However, the current climate and environment may be the only way to avoid this environment temporarily for some people who are already uncomfortable physically. Portugal's climate and environment need not be introduced too much, and it must be quite good. Some people even gave up their German identity in order to handle Portuguese immigration.
