立春 spring begins

Just found this picture in my computer, then thinking to share this cute event. Quite surprising that egg can stand on a specific days every year. Curious of how and why this could happen.

They said is the earth gravity will be stronger than usual...but how they calculate the accurate time and date? every year before the springs begin, all radio, newspaper, auntie or neighbour will talk bout this..

Above picture is I make the egg stand at my home and my shop. Two different place also can do the same things. I first try it is at my shop...starting quite challenge me coz quite hard to make it stand. Then at home i can make a tray of eggs(30) stand in just few minute. No matter is where and what position, the egg also can stand. There is a period of time the eggs can stand...I left the egg stand till the other day. Once i woke, all egg had "died", they no longer standing...Next year will play again...
