You are not qualified to denigrate oral English teaching.

Using FTs to teach oral English teaching in China is like teaching piano for the left hand and only the white keys.

It doesn't work.

One simply needs to visit any Chinese university and sit down with a few random members of the graduating class of English majors.

They cannot speak English.

Perhaps twenty percent of the class can hold a conversation. Perhaps five percent of the class speak well.

Bringing thousands of foreign 'teachers' to China to 'teach' English during the past two decades has been a marvelous business venture but an educational fiasco.
