A Teacher for All Ages: Starting with Taking Emperor Wu of Han as a Disciple

The author seems to think that the level of mathematics in the Han Dynasty was still at the level of the Xia and Shang Dynasties, and attempts to use elementary school word problems to refute the mathematical talents who represent the highest level of an empire. This plot is not only clumsy but also toxic.

I saw you say that those two pulleys on modern competitive recurve bows are for increasing draw weight. You've been watching too many marketing articles, haven't you? Those are called pulleys, do you understand what "draw weight" means? And they only draw weight when the bow is pulled to its maximum draw weight. They're designed to help athletes find the bullseye more easily.

The Qin bamboo slips contain a multiplication table; where does your sense of irrationality and superiority come from?

If someone argues and makes excuses when readers point out their mistakes, their writing is unlikely to be any better.

What kind of historical illiterate dares to write historical novels? Go home and read some books for a few years before becoming a national advisor.

This is utterly ridiculous. This absurd joke is probably from 200 years ago. Many people have said, "Stop with the multiplication tables! Do you really think our ancestors were clueless novices like the author?" The Han Dynasty, during the reign of Emperor Wu of Han, had already sent envoys to establish diplomatic relations with the Eastern Roman Empire.

There is no optimal solution for any system, only the most suitable system. Another delusional system that thinks it can completely dominate ancient times.

Not recommended. Judging from the title and synopsis, there are no highlights. History teacher? It's a good thing I time-traveled, otherwise I would be scolded for "misleading students". A quick Google search of Liu Che reveals he wasn't as unremarkable as the boy next door. He established schools, fought against the Xiongnu, and exclusively promoted Confucianism. Becoming an apprentice?

I wanted to give up after reading just the first chapter. It's not surprising that a multiplication table appeared in the Han Dynasty; there are records of it on bamboo slips unearthed from the Qin Dynasty. China's mathematics truly lagged behind the West during the Ming Dynasty.

How does the author interpret the view that the strength of the Han Dynasty led to the strength and unity of the Xiongnu?
