The Menace of Zhenguan

Many time travel stories deal with horseshoes, but horse shoes made of leather appeared in the Spring and Autumn Period and the Warring States Period, and iron horseshoes appeared in the late Jin and early Sui Dynasties. Historical data records that in the Sui Dynasty, Xiaoguoqi already had an official position specifically responsible for shoeing. But why didn't shoeing become popular during the Sui and Tang Dynasties? It was not a technical problem but a lack of productivity, which the Tang Dynasty could not afford with its limited iron output. Unlike other iron tools that can be recycled, shoe shoes are consumed by daily wear and tear. In terms of cost performance, it is better to replace the horse. Although farriers were popularized in China during the Yuan Dynasty, the technology has actually been around for a long time. Ancient China's science and technology was very developed and has always led the world. There are two points to pay attention to when traveling through cultural and technological streams: First, don't engage in existing technologies, but check the information first. For example, the Taoqiao saddle terracotta figurines unearthed in the Western Han Dynasty serve as evidence, and stirrups appeared at the end of the Han Dynasty and the Jin Dynasty, etc. Second, it must be in line with the social conditions at that time. The development of science and technology is gradual and cannot be leapfrog. We must consider whether society can bear the side effects brought about by scientific and technological progress. For example, if industrial textile machines are developed, old weavers will be eliminated. The social unrest caused by nationwide unemployment and bankruptcy is only one of them. The development of industrialization will change the social structure. The beneficiaries of the old system will not be willing to step down, and the emerging class will come to power. History tells us that the only final solution is war. If you really want to bring about the Great Tang Revolution, go and unify the world, Saonian. I hope the above suggestions are helpful to you.

This book was considered very good in the past few years. It can be seen that the author has the ability to tell a story well. However, the routines and jokes are a bit old, and I hope to see something different in your subsequent plots.

The new book "Long Live the Palace Master" has been released. Please support, collect and recommend it! Grateful!

I don't know if I'm sick or not. To read Tang Dynasty, you must watch the heroine Li Lizhi. Can anyone enlighten me...

I took a piece of paper to the production supervisor of our factory. He knelt down in front of me in shock and asked me what it was. I said it was an event, and he was shocked.

Let me say a few words after seeing Chapter 197. The first is that the two pandas are like spirits, and they are still chatting? It was really embarrassing to watch, and I was really incapable of accepting it. The second thing is that I didn't get married to Changle, and you, the husband, are here. Those who don't know think that Changle is a time traveler in the modern era. The description of the emotional drama is very poor! It's hard to see these two points right now.

It sucks, it's too perfunctory, damn it!

Okay, you can end it if you want, but the last chapter is completely perfunctory.
