Chinese believe,that you can stand a raw egg on end during the equinox. This happens from the notion that due to the sun's position between the poles of the earth on the first day of spring or fall, special gravity forces apply.

This isnt true beacause while it's true that on both equinoxes the earth's axis is perpendicular to the sun so day and night are are they same length. Theres no evidence that theres gravity or alignment changes during an equinox that would affect us on earth. Also, the hoax states that only eggs can stand on its edd.
