What do you mean by Hakkas ringing Ding?

This sentence means that there are new men in the family.

Hakkas ringing ding, also known as "ringing lanterns", is a traditional folk culture and belongs to a special custom in Hakka areas. This custom centers on "Tian Ding" (that is, the new male in the family), and carries out ancestor worship and comfort activities in the form of "lights".

Because the pronunciation of "Deng" and "Ding" is the same in Hakka dialect, Hakka people will continue to string lanterns in the ancestral home of the family according to the number of males born in the family with the same surname each year (usually in a dragon enclosure). These lanterns are bought or made by men's families, and are usually made of paper or painted paper.
