I am an old man. I have spent many years of college. I have studied several languages. I would like to focus on Mandarin. I want to have a conversation with the local Chinese. My knowledge of English is widespread and profound. I can explain the proper use of English words. I can explain why a word is the right word to use. 我一直在研究了数年的普通话。 但是，我想同中国人讲汉语。 我可以辨认出一些汉字。 我可以写只是一个非常少的字符。 我希望有人会使用语音聊天来帮助我。 而且我会很乐意帮助人们学习英语。
