I have learned that that you like modifies convenience store, or simply store in convenience store that you like.
And then, how about this one, English teacher that you like?
Can I say that that you like modifies English teacher, or simply teacher, too?
Thank you so much and I am sorry for my poor understanding😭
Little details like this are dependent on the specific grammatical school of thought you are studying.
Without a familiarity with that particular method of grammatical analysis it's not possible to answer your questions.
Doesn't your textbook or your teacher have an opinion on this?
