Republic of Colombia (Spanish: República de Colombia), referred to as Colombia. Colombia is the world's largest exporter of high-end emeralds and a holy land for roller skaters. The vast majority of Colombians believe in Catholicism, while a small number of people believe in Protestantism.

Colombia was originally the residence of Chibucha and other Indians. It was renamed the Republic of New Granada in 1831, the United States of Colombia in 1861, and its current name in 1886.

1. Hospitality and gifts

Colombians don’t like to invite guests to their homes, but once invited, it is customary to send flowers to the hostess during the first visit. When you are invited to a Colombian home, if time permits, it is customary to send gifts such as fruits, flowers or chocolates before arrival; if it is too late, you can send them afterwards, and you should also include a thank-you letter.

2. Etiquette

When Colombians meet guests in social situations, they usually shake hands as a courtesy. Men shake hands with everyone when entering a house or a group of people, and shake hands when saying goodbye. Women don't usually shake hands with each other; they clasp each other's forearms.

3. Taboos of belief

The "Sack Man", a new sect in Colombia, believes that the right side of the human body does many evil things and is the source of evil. Therefore, they covered the right half of their bodies from head to toe with sacks (hence the name "sack people"), leaving the left half exposed. No matter what you do, only use your left hand and don't use your right hand.

They are most taboo about "13" and "Friday", and regard them as numbers and dates of disaster and doom; they hate the legendary traitor Judas in Christianity the most; therefore, they celebrate the 13th on the Saturday before Easter every year. It is always customary to burn the ugly image of Judah to show that he can relieve his hatred.
