Question

How do they call present giver at christmas in China?

Answer 1

Becouse Chinese people are not Christian,China does not celebrate Christmas, so there are no special presents and  words for it. Chinese New Year  usually they do celebrate the end of January.But , gift-giver named Dun Che Lao Ren- Christmas Old Man.

Потому что китайцы(китайский народ) не христиане,Китай не празднует Рождество,

поэтому нет специальных подарков и слов для этого.Китайский Новый Год обычно празнуют в конце января.Но  дарителя подарков назвают  Дун Че ЛаоРен-Рождественский Старик.

Answer 2

In China, Christmas is not traditionally celebrated as widely as it is in Western countries, and therefore there isn't a specific term for the person who gives presents during this holiday. However, in recent years, as Christmas has become more popular in China, the term "圣诞老人" (shèng dàn lǎo rén) which translates to "Christmas Old Man" has been used to refer to the gift-giver in a similar way to how Santa Claus is referred to in the West.
