The sentence that confuses me from the reading is "...there are many perks to doing readings on a television show."
As an English learner, I was taught that "to + do" is the correct structure. But I've found and heard many times "to + doing" like the example above.
My questions are:
Does "there are many perks to do readings on a television show" sound right as well?
What are the rules and in what specific cases should I use "to doing" instead of "to do"?
Much appreciated.
