帮我翻译下英文！谢谢

1. I'm very happy to meet you, as the chances of us meeting each other is very small. Although I found you by accident, I cherish your friendship.Also, I love the times when we chat, it feels magical(?)as we are chatting in English from different parts of the world . Although my English isn't good, but I'd try my best to better communicate with you.

2.If I have the chance, I would really like to go overseas, but it is difficult for me. If I have the chance, I would certainly visit you.Maybe you are normally quite busy, but lets wait until you come to Beijing.

3.I hope you would point out the mistakes I made in our conversations.

4.Have you written a letter before?

第一段字不太了解你想表达的意思。。。所以就按照自己的理解了。。。见谅哈。
