  What is equally significant is that the sequence or order of the chapters is exactly the same as that in the received Laozi. The difference lies in the division of some of the chapters.  Chapters 17–19 of the received text form one chapter in the Beida Laozi. The same is true for chapters 6–7, 32–33 and 78–79. However, the current chapter 64 appears as two chapters in the Beida slips.  Altogether there are 77 chapters.  Each chapter is clearly marked, with a round dot at the start, and each chapter starts on a separate bamboo slip.
