The hourglass of time represents the passage of time, which means to cherish time. Hourglass is a kind of timing instrument. Time is measured by the amount of sand leaking from one container to another. It represents the passage of time. We should cherish it.
Time hourglass also symbolizes love, friendship and happiness. It means to be happy forever and cherish love and friendship forever! Time is disappearing, things are changing, time is passing, memory is disappearing, when missing is gone, memory is already extravagant, forgotten time will only sink in the bottom of my heart.
The archaeological term is “time hourglass”. Many ancient objects are well preserved in the isolated and unchanging burial environment. When they are excavated, they are the same as thousands of years ago, but they are soon oxidized and decayed. Just like the hourglass of time stagnated for thousands of years, the moment when the antiquities were unearthed suddenly accelerated.
