The han chinese are the source of many innovations. for example, the han developed paper, the seismometer, wheelbarrow, compass, and a ship steered by a rudder. which of the inventions listed do you think has had the most lasting importance, and why?

I think all are important, but I do believe paper has lasting importance. This is said because in present day we use other things then wheel barrows to store stuff, and we have boats and ships that are not steered by rudders. No one uses compass because of phones and seismometers are usually only used if your a seismologist. Paper is a daily everyday thing that people use.

Each mans success depends on his own hard work
