The movie Hero can be said to be a classic in an old movie. Qin Shihuang's domineering and heroic spirit of an assassin expounded the problems faced at that time, as well as Qin Shihuang's revenge and the attitude of the adherents of the six countries towards Qin. There are many classic clips in this film. Apart from the arrow penetrating the heart, the Terracotta Warriors and Horses of Qin Shihuang are magnificent. Qin Shihuang once mentioned that he destroyed the Six Kingdoms because he didn't want to learn the languages of other countries. This is actually just a simple excuse.
The reason why the six countries were eliminated was not because they didn't want to learn other countries' languages, but it reflected a very realistic problem at that time, that is, there were seven languages in seven countries in Qin, which was very inconvenient at that time. You think you go to Zhao to buy things, then you go to Chu to sell them, which requires proficiency in two languages, but if Chu doesn't want your things, you have to go to Qin to sell them.
In fact, reading history books shows that Qin Shihuang made a lot of contributions after reunification. The most important thing is that he unified the writing, unified the train track and unified the measurement, which benefited the people a lot. In other words, in the hero movie, he didn't want to learn a foreign language before destroying the Six Kingdoms. In fact, some achievements of Qin Shihuang's unification of the six countries are the description of unified words. As for the cause of the country's demise, it can't be said that he didn't want to learn foreign languages or other countries' languages, so.
This is just a manifestation of the film, in order to show the achievements of Qin Shihuang's unified writing.
