 　　"La Tumba Francesa" means "French drum". It is a song and dance of a black community prevalent in southeastern Cuba. 　　From the 16th to the 19th century, about 10 million African slaves were trafficked to the Americas. From the end of the 17th century, French colonists drove black slaves to grow sugar cane and coffee for them in Haiti. Under the influence of the French Revolution, Haiti broke out in 1790 to overthrow French colonial rule and abolish slavery. Later, some black slaves in Haiti moved to the southeastern part of Cuba Island one after another, and lived in a concentrated community. In the coffee farms on the outskirts of Santiago de Cuba and Guantanamo, Haitian black immigrants (also known as Creoles) often gather to entertain themselves with songs and dances, which gradually evolved into "Tumba Francesa". At that time, black people also formed some club-like "Tumba Francesa" associations in some cities in eastern Cuba. Towards the...

 　　Graphene is known as a "wonder material" due to its excellent properties such as high electrical conductivity, high thermal conductivity, and high strength, and it may revolutionize a large number of applications, including light bulbs, chips, batteries, touch screens, and smartphones and new energy sources. There are countless fields in which graphene can be competent. Let's take a look at the various uses of graphene! graphene integrated circuits 　　Due to graphene's super-strong transmission properties and very good thermal conductivity, graphene is also considered to be a material to replace silicon raw materials. Graphene should not be unexpectedly able to become the next generation of circuit board materials. As early as 2011, a foreign team developed a state-of-the-art "graphene transistor" and integrated the newly researched transistor into a new electronic circuit for experiments. Some of the scientific teams at the company developed the world...

 　　If you ask the locals what is the most traditional food in the Czech Republic? Almost everyone will tell you that it is barbecue with sauerkraut and steamed buns. I don't know the origin of this delicious food. In the Czech days, no matter where you go, it seems that such a golden combination is indispensable on the table. Sometimes the commonly used pork is replaced with duck, beef or other fatty meats, the sliced ​​steamed bread can be replaced by potatoes, and there are many varieties of sauerkraut. Such a combination makes us newcomers to the East feel fresh, but at the same time feel a little greasy. High energy and high protein is indeed a tradition in Czech cuisine.

 　　When it comes to the United States, people will immediately think of the beautiful scenery of Hawaii and the skyscrapers of Chicago. However, when I came to the United States this time, in addition to these natural and cultural landscapes, what shocked me the most was the kind of American condensed on the national flag. Hot emotion. 　　Arriving in Chicago by plane, as soon as I walked out of the international airport, a magnificent sight immediately caught my eye. In the spacious square, a row of flagpoles were erected high, and the American flags hung on them fluttered in the wind. At any location, the clattering sound of the flag flying can be clearly heard, as if to remind everyone that this is the United States. 　　I thought this was just the need for the airport to serve as a window for publicity. Later, I found that in the clean and green Chicago, this blue star, red and white flag can be said to be flying all over the city and can be seen everywhere. Walking on the street, ...

Another big country in the world, the United States, has a short history, but at least 100 CDs are needed to reproduce the American spirit in the pioneering century of the West. Glory and dreams are woven into a big flower basket. 　　There would be no West without cowboys, and there would be no America without the West. Europeans who immigrated to America have been following the sun—westwards and westwards. 　　Vast grasslands, vast deserts, strange canyons, lonely towns, cowboys riding horses, facing the scorching sun. Shopping in banks, bars and gunmen, American Westerns take you into an unfamiliar world in a unique way. 　　The first American Western DVD I bought was "Slaying the Dragon" starring John Wayne. An old cowboy was already fat and had a big belly, but he didn't have the pride of a cowboy except that he was quick to shoot. It was 2001, and I h...
