The rust update for gong and boomer really looked like something that the Chinese would use for their Chinese New Year.
One may think whether it was meant to celebrate Chinese New Year which is on 25 January 2020.
When the boomers were ignited, they were shooting fireworks in the sky.
The amazing sight when the fireworks were viewed from a distance.
The fireworks were beautiful when it was night time in the game.
The updates may simply be a way to celebrate Chinese New Year.
