However, due to the influence of religion, the western world is very shy about this number. Legend has it that Jesus had his last meal with his disciples before he was killed. The 13 person who attended the dinner was Judas, a disciple of Jesus. Judas betrayed Jesus to the Jewish authorities for 30 silver dollars, which made Jesus suffer greatly. The last dinner was attended by 13 people, and the date of dinner coincided with 13. From then on, "13" was regarded as a symbol of misfortune and a synonym for betrayal.
Westerners try their best to avoid contact with "13". In the Netherlands, it is difficult to find the house numbers of buildings 13 and 13. They replaced 13 with "12A". You can't find 13 rows and 13 seats in British theaters. The French are very clever, and there are generally walkways between rows 12 and 14 in the theater. In addition, people are also taboo to travel on 13, even more taboo to eat with 13 people, and even more unacceptable to 13 dishes. If the 13 of a month falls on Friday, it is a very unlucky omen, and it is called Black Friday.
