the grammar or the order of this sentence is not correct. And just only one sentence ,so I don't know its meaning either.Sorry. Or it is to say ‘居然到了他的嘴里’。

I just search the“Wade-Giles”，which was used before 1958,and after that we begin to use Chinese phonetic alphabet.

I think you should learn Ping Yin first . We learn English from the beginning of "A,B,C,D....",and then met phonetic symbol, and included some simple words. I think your phonetic symbol is similar to our Ping yin in some way.But it is important to keep them in your head .somebody sometimes may notes Ping Yin under the word they don't know ,just like you ,prefer to write in your way to the unknown words. However ,I had never used this method to learn words ,I will look at the phonetic symbol first how to read it ,and remember the pronunciation,then try to remember the word.
