Kyudoku :- Introduction

Question

This is a Kyudoku Puzzle. I have made the rules myself.
There will be numbers in a grid. You just have to circle nine unique numbers (1 to 9) such that each row and column has sum of 9 or less. In some puzzles, one or more circled numbers may already be given.

Here is the real puzzle.

Note:- This is not a puzzle of my own. There are puzzles similar to this you will find in the internet, but it has not been introduced that well in PSE before.

6 and 7
There are only three ungreyed 6s and three ungreyed 7s in the grid now.

Now we know that
