How do you touch eggs during the summer solstice in Ningbo?

It seems that Ningbo doesn't touch eggs on the solstice of summer, but in the long summer. In Ningbo dialect, it is called "leaning on the eggs of long summer", which means "touching". "Relying on eggs" is a child's play, but it is very learned. An egg has two heads, the pointed one is the head and the round one is the tail. According to the rules, when beating eggs, the head of the egg rests on the head of the egg, and the tail of the egg hits the tail of the egg.
