Personally, I prefer Spain and want to apply for Spanish immigration, but I don't know which city to choose. Please let me know, thank you!

As far as the current immigration situation is concerned, first-tier cities have the most return on investment value, such as Madrid and Barcelona, because Spain is a place to buy a house, and the real estate of immigrants can be rented and sold, with a population base. Compared with the two cities, Madrid should be the political center of Beijing, and Barcelona is like the tourist center of Shanghai's economic center! At present, more people from China go to Barcelona.
