Numbers that don't appear in international hotels

Foreign hotels are relatively shy about Room 420, especially in the United States, where digital signs of Room 420 are rarely seen.

The taboo of Room 420 abroad originated from a marijuana accident in 197 1. It is said that Xiong Haizi and his group, who were studying at san rafael High School in the United States, gathered at 4: 20 p.m. to smoke marijuana in front of the Louis Pasteur statue at the school. Because of the sensation at that time and the actions of a group of students, April 20 every year became World Marijuana Day. So in the past, many people who smoked marijuana abroad liked to choose Room 420. They not only regarded Room 420 as an anniversary, but even regarded Room 420 as a memorable place. Therefore, some hotels have cancelled this room or replaced it with other symbols. It is also to avoid some psychological risks.
