TOPIC 1: What makes my culture different from others? 
Many Germans believe that there are no differences between Chinese and Vietnamese. It is true that Chinese culture has a great effect on Vietnamese culture. However, it’s the language, which shows the biggest difference between two countries.
Vietnam is located in the center of South East Asian and shares a part of a border with China. For a thousand years, the Chinese Empire had invaded occupied Vietnam, which explains why Vietnamese hadve adopted many things from Chinese culture. However, the Vietnamese language has its origin from Thai. Both languages share the same grammar system and most of basic Vietnamese words came from the land of elephants.
Vietnamese was first written in “Nom”, which looked similar to Chinese alphabet. After Vietnam became a colony of France, the written language changed because of an invention of a French priest. He found out the way of using Latin Lletters to write down the expressions in Vietnamese. During the war against France, this system of letters was used first of all by the French, then by the Vietnamese S students. Nowadays it has been developed into a national alphabet for everyday uses, including business and education.
In a few words, the Vietnamese language is a combination of many different cultures. That makes our language rich. Next time if you would like to distinguish between a Chinese and a Vietnamese, take a look at their notebooks and you will find it out!
