Unfortunately the language toolbar is not functioning properly so I cannot highlight your mistakes, but must just delete and rewrite. Some areas I cannot correct at all because the cursor will not engage. I cannot always change the colour of my own text either. 

It is good to see you trying some relatively advanced vocabulary - you can't progress if you don't experiment. I haven't corrected your spelling, you can use Microsoft Word for that. I have put question marks in where I was not sure what you wanted to say. Good luck with your language learning - Hugh

Saying hello to everyone [Hello Everyone would be more colloquial] 

Hi everybody, I really want to meet some friends and chat in English here and learn some spoken English usage.
China is a developing country. This means more than just economic development, but also development of manegement methods and people's ideas about modern society. In fact, China has to face a whole new revelution of the mind, which has been generated mostly in the West. To know more about each other, breaking language obtacles is essential. For Chinese, learning English is a way to understand the real thoughts foriegners have about China, and a clear covery? that China is willing to become a part of the wider world.  
After not more than 300 years studying science and struggling for democracy, Western society has become what it is today. Nowadays these developed coutries have begun to put great effect? into developing areas?. Ever since, they have had quality products, advanced ideas in manegement, and cultural diversity. China has begun to learn from these neighbours and indeed this has speeded up its economical development, but cultures of East and West converge? is much more difficult. Obviously exchanging some of our ideas would help us to achieve that goal, and as a converstion between two persons of different backgrounds, we would have much more fun and suprise.
Beijing is a modern city with ancient history, its history stories and unique cluture attracts many people coming here, I am sure you'll say wow if you come to Beijing, for Chinese are always warm-hearted and will try their best to let any guest feel at ease and be happy in China. Please feel free to ask me if you want to know more about Beijing!
Welcome to China! 欢迎来中国
