I am in Chinese是“我在中国人的”意思吗

I am in Chinese是“我在中国人的”意思吗 I am Chinese.VS I am an American.有人说：只有I am Chinese.没有（或者说不正规）I am a Chinese.那为什么有I am an American.(我认为有)顺便问下在“I am Chinese”中,Chinese是名词还是形容词? 是i am a chinese 还是 i am chinese 英语翻译翻译：我是中国人我只想知道是“I am a Chinese”还是“I am a chinese people”， I am Chinese.中Chinese前用不用加a? I am Chinese who live in mainland China这个定语从句这个定语从句的先行词是chinese 还是 i .我觉得是I .请问我的思路错误吗?.我还认为,如果要体现chinese为先行词的话,那么句子该是非限定,例如：i am ch I am at/in the office 是用in还是用at ,我在办公室 i am not chinese i am nativer chinese How to learn Chinese?I am in Canada. i am not good at ----(write) in chinese. I am looking for partners in major Chinese i am in dalian,who can teach me chinese? I am a teacher aid in the chinese language. I am chinese who live in mainland china.和I am chinese who lives in mainland china.那句正确 I am a chinese说法为什么不对?据说I am a chinese是错误的说法（新概念里就是这么说的）,因为chinese在此做形容词,所以前面不能加冠词a.但是词典中chinese也可做名词,意为“中国人”,并且 英语口语中I am in I am from China.的同义句是I am a Chinese.还是I am Chinese.还是都行
