1. Time Advance: Archaeological findings prove that the silk book Laozi was buried about 2 170 years ago, about 50 years earlier than the oldest known Tao Te Ching, and archaeology also proves that the silk book Laozi was copied earlier than the burial time. Comparing the silk book Laozi, we can see that in order to avoid the taboos of the five emperors, the Tao Te Ching changed the word "bang" and "constant" to "constant", "qi" to "open" and "qi" to "open".

2. It's not isolated evidence: Although the silk book Laozi of A and B was unearthed at the same time, it is obviously different in font, copying form and copying date. Although they are different, their thoughts, contents and themes all belong to a system, which is quite different from Tao Te Ching. They are kept in the same bookcase at the same time, at least in the next chapter.

3. Self-certification is fundamental: It has been found that due to hundreds of changes in the original book, the handed down Classic of Tao Te Ching has caused extremely huge inheritance losses, and its remaining ideological wisdom is also rare in the original book, which not only caused the great scientific achievements of the original book in the natural science field to be completely destroyed, but also completely contradicted the theme in the social science field, such as the original intention of "inaction".
