Classic Sudoku(001)

Rules: Classic Sudoku rules apply.
The author of the puzzle is my friend 胡蒙汀(Hu Meng Ting) from China. I hope you like it and would appreciate any feedback.
Special note: If you use one of the observation techniques of Classic Sudoku, you can easily complete this problem, so the difficulty of 3 stars is given. At the same time, the three puzzles posted earlier use this similar observation technique, and a few Sudoku in various forms will be released later, and then this technique will be appropriately developed through the forum.
Solution code: Row 1, followed by coloum 5.

This is one of the most remarkable Sudoku puzzles I've ever seen - previously I thought that applications of the so-called Phistomefel's theorem could always be side-stepped by other easier techniques. I've double checked using solvers and this is not the case with this puzzle, which makes this the first time I've seen genuine novelty in a Sudoku in as long as I can remember.
I think some of the petty comments and vindictive ratings here are very unfortunate, and certainly not what this puzzle deserves!
