It describe wu nation in three kingdoms. When chines fight each others. A military adviser from shu nations. cause he is reality knowing that there is no peace forever. So he lead china to become three nations. There is no win because when two fight the rest win but all of them want to win so all can not move to be blance They all come from a dynasty. so there is name and content problem. It is like game theory. sometime we dont need to seek win all.
I like she can slap the instrument in the end.
