I was in Hong Kong during the Christmas run up. Lots of familiar Santa displays, but much of the “shopping mall” music was totally unknown to me - vague things with lyrics like “Christmas is Coming.” “It’s Christmas, It’s Christmas” sung to unfamiliar tunes. There were also familiar carols and things like Santa Claus is Coming to Town and Jingle Bell Rock, but I don’t recall anything winter or snow based. (It didn’t feel right to me!)
