This is the 3th part of the series of dividing areas.
“老子” Sudoku

1.Fill in a number from 1-9 in each region, and make each row, column and region have no repeated numbers;
2. A white circle indicates that the 4 cells arrounded belong to the same region,All white circles are given;
3.Whenever a cell has only one adjacent cell in the same region, the numbers in both cells are given outside the grid in the direction of the adjacent cell (in the correct order).

“老子”（Lao Zi），was born in Kuxian County of Chu State in the late Spring and Autumn Period of Zhou Dynasty in China (571 BC-471 BC), one of the world's one hundred historical celebrities, ancient Chinese thinker, philosopher,literary and historian, founder and main representative of Taoist school.In Taoism, he is revered as the ancestor of Taoism, and he is called "the Great Laojun." The core of Laozi's thinking is simple dialectics, which advocates the rule of doing nothing, teaching without saying, and the principle of the opposite. Lao Tzu is the ancestor of Taoism's dual cultivation of both life and life. Author of "Tao De Jing" (also known as "Lao Zi"), is one of the world's most widely published works.
Solution code: In the reading direction (from top to bottom, from left to right), the content of the irregular area where R6C8 is located, and the content of the irregular area where R8C6 is located, a total of 18 grids(for example, in the example, the content of the irregular area where R3C4 and R5C4 are located: 12364754231567).

Thank you for your feedback. It is true that there is a big difference between this series and BDblock, the author has tried the "black △" symbol and "white ○" symbol to indicate "same regions" and "three different regions" in "墨子", similar to the "black dots" of BDblock "T" or "X" division. Of course this is just an attempt. Use "white dots" to indicate the same regions and "black △" to indicate different regions. This is where this series borrowed, so you can try further.

BTW, I don't agree, that the next series is really based on bdblock. The rules look similar, but the character of the puzzle type is completely different.

I see no problem with the solution code. I would keep it as it is.
I suppose most users will use penpa+. I suggested to Swaroop to let the author write the success message. Then you could give the solution code there, and the solvers could copy and paste it. If this is included in a future release, such problems will be solved.

The author "真笑（洪卫华）" produced this Chaos Construction series in 2017, and the idea is not necessarily very mature.If you like, you can use these rule sets to make some different puzzles, thank you very much!

Thank you so much for your kind feedback! In the process of testing this series of puzzles, I found that even after filling in all the numbers, it may not be possible to determine a specific area, and further reasoning must be made through the rule set. I think this is very interesting. The "庄子" and "惠子" in this series are more obvious. So I decided to verify the answer based on "all the contents of the area corresponding to a specific cell".
I am not sure whether this method of answer submission is necessary, so I welcome more effective and concise answer submission methods.

Marcmees -I think- wrote about this a week ago. Part of solving this puzzle type is that you find out the exact shape of the regions. Actually: in some of these puzzles you find all the numbers in the grid before you know which cell goes in which region.
I agree with Marcmees that this is a very valid reason to keep these solution codes the way they are.

I like the puzzle-type, but I think the code is too complicated. Why don't you ask for entire rows or columns as usual?

Added Chaos construction tags.

Repaired title,From Phistome's "https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=0004D4".

I am glad you like this series, thank you for your kind feedback. "Laozi" is indeed easier than "Zhuangzi". The next series may draw on the puzzle "Bdblock" and create around "△" and "○".

@Dandelo
Thank you very much for your suggestions on the name of the puzzle. I would like to learn from Phistomefel's Chaos Construction (ID=0004D4), or Jigsaw Construction, Irregular Construction. If you have better suggestions, please let me know, thanks again!

I agree with the others. Challenging, but not too hard. And, as always, a nice solution path.
I think 老子 is different from 庄子, but since I don't understand Chinese I couldn't see the type from the title. Maybe you should add German and/or English titles. IMHO "divided area" is too general. Usually for such puzzles, where you first have to construct the grid, the name contains "reconstruction".
