Can you find a job by immigrating to Europe? What is the most profitable job?

There are 32 countries and regions in the EU, and each country has its own unique side. Greece, Malta, Portugal and Spain, which are popular at present, belong to southern European countries. Southern European countries are mainly famous for tourism. Many people in China do tourism-related jobs, such as tour guide, ground connection, house rental, air ticket reservation, car rental service and translation escort. The number of tourists in China is very large. China people also have advantages in local tourism services and real estate. For example, Greece can buy a house for immigrants for 250,000 euros, so many immigrants to Greece will buy some old houses and bring them back to China to sell to immigrant applicants. But it should be noted that if they just immigrate to the past, they should not think about unemployment benefits. I saw some netizens say that "you can receive unemployment benefits if you immigrate, so there is nothing to worry about". Because you just reported that you can't get unemployment benefits without making any contribution to the country. The so-called contribution is paying taxes. Just like China, you need to pay taxes for a certain number of years before you can enjoy unemployment benefits. Some countries also stipulate that immigrants holding green cards can only do business and cannot work unless they apply for permanent residence or naturalization in the European Union. The national population determines the competitiveness of economy and employment. The greater the competition for national talents, there are many small countries with small populations in Europe. The job is easy to find, but the salary is not particularly high. The average minimum monthly salary is 700 euros. Of course, this is the minimum standard. If you have certain work experience and ability, it's more than that. Prices in small countries are also low. For example, in Malta, a family of three can live a good life by spending 1000 euros a month, and a small country can't make much money. All local residents. In order to enjoy life, they won't even let him walk faster, just for the peace of life. The opportunities in big countries are relatively greater, but it is hard to say what job is the most profitable. It's hard to say whether you can become a champion. The most important thing is whether you are competent or not. But it can be noted that blue-collar technical unions earn much more money than white-collar workers. In foreign countries, having skills is very popular. The domestic population is too large, and the labor force is worthless. You are very popular abroad.
