Among the research results of the Tibetan archaeological team, the first thing they discovered was a Neolithic site. According to us, it has been eight thousand years now. Archaeologists in Tibet first discovered ancient accumulation, accompanied by traces of fire. They took these back to the institute and found that they were unearthed 8,000 years ago. This is the earliest stone tool found so far. It is also a very valuable stone tool, which makes the archaeological team very happy. We can also imagine that they will find those useful values through some research and promote our historical process. Among the ground stone needles discovered by the Tibetan archaeological team this time, we were completely stunned by the wisdom of the people at that time. We can observe that the appearance and feel of this needle is very similar to the needle we use now. And in this discovery, we can see that this stone needle is perforated, which is similar to the needle used in our daily life, but not as smooth as it is now, but we really can't compare with it in technology. At that time, the needle could only be ground, but now it is ground by machine, so it has the present smoothness. The wisdom of the ancients is really an example for us to learn. They have gained the ability to survive through step-by-step practice. In order to live a better life, they created countless daily necessities that we still use. It's really amazing. We should also learn from the ways of the ancients and be brave in doing things.
