  我这周在坡特兰拍一些关于访谈的视频，看望几个人（朋友），还计划看学语言的记录片。十一月我会去上海，会在中国那里（cause you said you will go to Shanghai, so to make it more logical, it's better just say "i will stay THERE for some months"）再待几个月继续学习，、（“ctrl”+"\" we use this punctuation when listing a few things, for example, "I like banana, apple and grape.我喜欢香蕉、苹果和葡萄。"）拍摄。

"a" correction and comment

"a" words need to be deleted

"          "replaced the order

I  can see you have learnt Mandarin for some time and you can deal with most of the grammar and the use a correct word in the sentence. However, your title is "the business trip in 波特兰 " with half of the content is about another trip in China, so, I suggest you to write some interesting stories about your businesss trip there so as to make the writing focused:) If you got any confusion of my correction please contact me.

"会在中国再待几个月继续学习，拍摄"这两个词这间不用“，”隔开的！
