I learned a lot from traveling and living in Zaragoza. We must not carry liquids when entering the aircraft. We can only have food. It is wise to take something to eat at the airport. Probably no more open on arrival. In other countries, it very much depends on when something is open. I learned a lot of practical things in school. Work at Solidswork. We also had an electrical cabinet connection for a three-phase motor. I also learned that it is necessary to know at least the basics of understanding. You need to take care of your stuff. The professors reminded us to be very careful about things in Barcelona. During this time where Covid-19 reigns, it is advisable to have plenty of masks. I also learned a few Spanish words. Spanish is very interesting and is also the 2 most widely spoken language in the world.
