sorry to say this but without the tone marks this is not pinyin . And pinyin is not Chinese.Pinyin is a pronunciation guide for Chinese characters. So there is no way to comment on your post the way it is here . And commenting on pinyin by itself is not really useful . I suggest you begin to learn the Chinese characters along with pinyin . Then you will be on your way to learning Chinese and can get a lot of useful help here .
