Answer:
圣诞老人 [shèng dàn lǎo rén]
Sheng Dan Lao Ren mean 'Father Christmas' or Santa Claus. The name is derived from the Chinese name for Christmas, 'Sheng Dan Jie' (with 'jie' meaning holiday), combined with the phrase 'lao ren', meaning 'old man'. So, the literal translation would be 'Christmas Old Man'.
