grammar - "I remember the advice he gave to me" Why add preposition to?

While I was reading a book, I stumbled upon a sentence "I remember the advice he gave to me".

From my understanding, give can be used in two ways.

First. Give + IO + DO. For example, "He gave me an answer."

Second. Give + DO + to IO. For example, "He gave a book to Jane."

So, I thought the correct sentence should be
"I remember the advice he gave me"
But the sentence includes preposition "to".
Which one is right? And why is it?
