To further prove this point, a couple of years later, a new emperor demanded that Su Song's son Su Xie rebuild the grand clock. After several years of attempting to rebuild the water clock they had quite plainly failed. Since they weren’t able to replicate the clock they decided that Su Song had left out key parts in the building plans, so no one could have a clock such as his.
All this suggests the greed people can have for knowledge. The complexity of Su Song's project in the first place indicates some of that desire. If he really did leave out parts of the building plans, it further shows that he wanted to be alone in his accomplishment. Then, even though no one from the Jin army could rebuild the clock they took it anyway, illustrating the power the desire for knowledge had over them. But greed comes from having something amazing that’s more advanced than what everyone else in the world has.
People today have tried to rebuild the water clock but the best replica we currently have is about five feet tall and doesn’t actually keep time
So even with today’s technology Su Song’s astronomical water clock is unattainable. Whatever implications its story suggests about human nature, Su Song’s three story astronomical water clock is an amazing invention for his time and ours.
