What does the birthday girl mean by putting cream on her face?

Applying cream to the birthday girl's face means "increasing happiness and longevity"

In addition to everyone's joy, members of the Pingxi village resident team also distributed cakes to the birthday girl and the old people involved in it in turn, and expressed their most sincere wishes to the birthday girls. During the process, the old people ate the cake happily and did not forget to put cream on the birthday girl's face, which means "adding happiness and longevity". Seeing the pinch of cream on the faces of the birthday girls, the old people smiled sincerely.

There are two explanations for the meaning of cream:

1. One explanation is that cream comes from birthday cakes, which are only available on birthdays, that is, only once a year, so everyone paints this happy time on you with sweet cakes. I hope you will have a successful career in the year after tomorrow.

2. Another explanation is that the homonym of "paste" is "new here", so some people put paste on the face of the birthday girl, which means "adding happiness and prolonging life, being new here".
