My father raised us to adulthood. We left home to go to school and work when we were adults. We often forgot our parents because of the busy work. However, we didn't know that our parents raised us with youth. They needed the most company when they were old. The highlight of this work is the hourglass. The hourglass is above the father and below the children. The father left us all his life (he spent his time, energy and effort on us without reservation), we can't give time to our father. Often go home to see, don't let our father alone empty nest. This work is made by hand in the way of frame-by-frame drawing and freeze-frame shooting, and finally synthesized by computer. This work uses FL, PR, AE and other software post-synthesis.
