Step 1: Look at the nine numbers first. Which number appears more often, nine appears six times and seven appears five times, so let's start with these two numbers.

In this way, 7 and 9 in the table will be filled in, and these two numbers can be ignored in the future.
Step 2: See if a number appears twice in lines 1-3, 4-6 and 7-9, so that we can infer where another number appears in these three lines or columns. For example, there are 2 in columns 1 and 3, so it is not difficult to conclude that the other 2 is located at the intersection of row 2 and row 2. My habit is to be horizontal first and then vertical.

In this way, the form is filled with many figures.
Step 3: My habit is to start from the upper left corner. I will find that if I want to satisfy the existence and uniqueness at the same time, I can infer all the numbers.
