Why is hallommig so popular?

The reason hallommig became popular was the Russo-Ukrainian war. Because it was a video related to the Russo-Ukrainian war that was very popular on Douyin, the BGM in it was all hallommig, which gave the Russo-Ukrainian war a sense of occasion and became popular. Hallommig is a popular song sung by Canadian female singer Celine Dion. The lyrics and music score were written by James Horner and Will Jennings, with the latter responsible for the music production.
