Christmas Sudoku
1. Classic Sudoku rules applied;
2. Skyscrapers:Digits outside the grid represent the number of skyscrapers that is visible from that view point. Higher skyscrapers hide lower skyscrapers;
3. Renban:The numbers on each Christmas leaves form a set of consecutive numbers(Including Christmas tree, 4 groups in total), and the numbers on each snowflake form a set of consecutive numbers, and the number sequence is not limited.
Notice:A total of 5 sets of Renban!
Merry Christmas!:-)
Solution code: The numbers on the longest Christmas leaves leaf from bottom left to bottom right (9 grids), and the numbers on the snowflakes from top to bottom, from left to right (7 grids), a total of 16 grids.

Great puzzle! I really enjoyed the extra logic resulting from those Renban groups :-)
I think it might be more helpful to use the "Renban" tag since it links to more puzzles.
Also there is a skyscraper icon as well as the German "Hochhausblöcke" tag, which link to more skyscraper puzzles. (It will make it easier to find skyscraper puzzles this way).

Thanks your kind feedback,I have always wondered whether the logical distance of this puzzle is too deep. In fact, the skyscraper and Renban cross-interacted several times. The description of the problem-solving code has been modified.

This was such a difficult puzzle for me. When I saw the initial rating I thought it would be a quick fun thing, but here I am over a day later, finally done. There are just so many things going on to keep track of. Beautiful things, but difficult to spot.
For the solution code, I would suggest switching the wording of the second part to "from top to bottom, from left to right" because to get the solution right, you need to start with the top row, not the left column.

In order not to spoil the festive atmosphere of Merry Christmas, I decided to uncover a layer of tulle on the stormy Christmas tree. Here is a clue to congratulate "Merry Christmas!"

I might just be really bad at Renban-type puzzles, but I think this is really hard! And fun too, but mostly hard.
******There is a good interaction between the 5 grid Renban and the 6-story skyscraper in C2, you may have overlooked it. :-)

maybe I got blinded by the blizzard, but it felt harder than 2 stars. Nice. Thanks
******thanks your feedback，increase difficulty.
