a good advice? a good piece of advice?

[optimistic pessimist]

Dear all,

Do you say, "a good advice"? Since "advice" is an uncountable noun, I think "a good piece of advice" is correct. However, there are five hits of "a good advice"in COCA.

Thank you!

In my opinion, "a good advice" is incorrect.

It's also common to say, "He gave me some good advice" for one piece of advice.
