Hey everyone! My name is Kuluto and I am from china. I lived in Hangzhou city, it is one of the important tourism cities in China, famous for its natural beauty, history and cultural heritages.I am learning English 、Portuguese and German because I am interested in these countries cultures .
People, living in different ages, often have different ideas of the same thing. For example, in the 1960s, people were more likely to get married and lived more peacefully! But with changing times, we changed. Now people are more eager to get in touch with more new things from around the world. I have always wanted to make some friends all over the world. I need to study. If i don't offer myself to the unknown, my senses will dull, my world will become small and I will lose my sense of wonder.
I want to make some friends here, in order to improve my foreign languages, and to especially improve my oral.
I know my English is poor, I would like to learn it, and with some effort, change it by myself.
In return, I will help you to improve your oarl Chinese!
I hope we become good friends, I hope to give you more help.
best of luck!
