I come from Jiujiang, Jiangxi. In my spare time, I took wedding photos for many relatives and friends. Found an interesting thing. That is, on the wedding day of the newlyweds, before the newlyweds meet their in-laws, both sides have to wash their faces before they can meet. Cut the crap and go straight to the picture above:

The first family (actually my cousin, haha)

My aunt and uncle have to wash their faces in the other room. You can't meet without washing your face.

Second group of families

Friend, I wish him happiness and early birth.

My friend's father, washing his face in the other room, can't meet until after washing.

The third group of families:

He is also my relative, my uncle's cousin. People who wash their faces with water are also particular. It's the kind of gentle and peaceful, with high family status.

Washing face water by a gentle elder with high family status means that husband and wife are in harmony and people are prosperous.

Bring my aunt water to wash her face. Before washing her face, my aunt hid in the room and couldn't get out.

For such folk customs, I personally think so. First, wash your face to show respect for each other. (But this reason is not sufficient. If it's just respect, why hide in the room and wait until you wash your face before you meet? Second, washing your face, I guess, means a makeover and a qualitative leap in identity. From this moment on, a girl means to become someone else's daughter-in-law, and her parents begin to become someone else's in-laws at this moment.

Of course, this is only speculation, and there is no strict textual research. Welcome netizens to leave a message for discussion. Is there a similar wedding in your hometown?
