In some areas, it is a folk custom to boil eggs on the back of the birthday girl when celebrating her birthday, which means to eliminate disasters and increase happiness (eggs cross the bridge).

There is also a way of "crossing the bridge with eggs" as a way to make people happy at the wedding (putting an egg into one cuff of the bride, squeezing it through her chest and taking it out from the other cuff). Others asked, "Is it soft?" "Not bad," said the groom.

Everyone has heard of "crossing the bridge rice noodles", but have you ever heard of "crossing the bridge eggs"? Maitreya has a fully-automatic high-tech chicken farm, and the fully-automatic chicken house is operated automatically from constant temperature, feeding, manure cleaning to egg picking. Eggs are automatically transported from the henhouse to the egg collection room through an "overpass" (central egg collector), which is called "bridge egg".
