I feel that Barcelona is different from many other European cities I have visited before. Barcelona's first vision is a bit old and vicissitudes. However, when you go deep into it, you will immediately find that she has retained most of the unique culture, but also injected new elements. It is said that Spain's economy ranks third to last in Europe today, but the pride of its human skeleton has not been extinguished. They still retain in their hearts the sense of superiority of their ancestors in driving the invincible fleet and dominating the world. Barcelona has not only a free and comfortable life in the West, a good natural environment and friendly interpersonal relationships, but also a strong sense of history, which many European cities do not have.
