Islam, Christianity, Confucianism, and Buddhism influence cultural practices in Indonesia. Indonesians are very superstitious, mystical, conservative, polite, and courteous. They love to make friends. Indonesians value harmony, smile, and a humble demeanor. They greet people with a handshake. You should never extend your hands to a Muslim lady unless she initiates it. Indonesians move in the groups with an active community sense; they seldom do things alone.
