—Edwin Powell

人生来具有五种感官，他们探索周围的世界并将这种冒险称为科学。

——埃德温·鲍威尔

Edison was an American scientist. Every time he thought of some experiments, he would try them. When he was a child, one day, he saw the hen hatching, he asked his mother curiously：“Mom, how can the hen sit on the nest and not move？” Mother happily said: “The hen is hatching.” Edison was very happy to hear his mother's words. He took some eggs at home, built a nest, spread thick grass on the ground, put the eggs on the nest, and sat on the nest by himself.Before long, it was getting dark, and his family was very anxious. They looked around for Edison and finally found him. His family was angry and happy and said, “What are you doing squatting on the nest？” Edison said, “I squat on the nest to hatch chickens.” His family said: “What chickens do you hatch? If you don't give them to me, go home quickly.”

When we find something interesting in the future, let's do it together. Maybe you will also become a scientist! But we must pay attention to safety!

Huawei 5G technology means more than

quicker communication

Supported by the Huawei technology，Vodafone Espana commercialized the first 5G mobile services in Spain on Saturday.The 5G network can make a huge difference.About half of the population in 15 major Spanish cities including Madrid and Barcelona are involved，which makes the country among the first that used 5G services in Europe.

Vodafone Espana's using the Huawei 5G technology means not only communication 10 times faster in Spain，but also a step closer to the excitements like autonomous driving，tele­medicine and virtual reality in everyday life.Another thing that is certain is that the United States' effort to block the global 5G technology leader Huawei from the 5G network market at their expense will not work.

It is a fact worth mentioning that Huawei has been in cooperation with most of the major mobile operators across Europe.Spain is not the first in Europe to use Huawei technology，and is surely not the last one.
