Are all hand gestures universal?

Cultures, traditions and symbols vary depending on the country. One of the standing pillars of etiquette is to be polite and respectful towards people and the surroundings ✅ ❗️I always advise everyone to make proper research on cultural dos and dont’s when travelling to a foreign country as many habits or gestures might have a completely different (offensive) meaning than what we are used to. What other hand gestures have a different meaning depending on the country? 🤔
