Fun puzzle! Solution code was painful though, for future Sudokus I'd suggest asking for the contents of two rows or similar.
******Thank you for your feedback. In the next puzzle, I will simplify the solution code. I appreciate your suggestions and I will consider it seriously.

This is really a great puzzle type. Also the non-sudoku solvers should give it a try.
But the sudoku tag should be added. Maybe you or 真笑(洪卫华) should find a good name for it, in English or German, and add a tag for these puzzles. It could become a popular variant.
Maybe "Chinese Sums Sudoku"? Because it has a lot in common with Japanese Sums?
******I'm glad you like this variant. The general puzzle name is already under consideration. Chinese Sum Sudoku is a good suggestion, thank you very much!
