The Han Dynasty changed a few notable policies that were established.
1) The Qin Dynasty banned Confucianism (belief that people are naturally good) and rather focused on Legalism, but the Han dynasty lifted the ban and allowed it to be practiced once again. The Han Dynasty used Confucianism as a model by which to govern.
2) The Han Dynasty reversed the autocratic policies of the Qin Dynasty. The Qin Dynasty was ruled by a single emperor (which is an autocracy) but the Han Dynasty allowed several leaders to rule and have power rather than one man.
I'm sure there are more, but these ones should do. Hope this helps! :)
Idk. .......................
I believe the answer is C
It is said that someone in the woods fire their gun three times hide until all the soldiers came toward them then surprised attacked the soldiers that came to the woods to check where the firing came from. Then again this is just a rumor, I don't necessarily know what exactly happened but you should get at least an idea of what happened.
