I was born and raised in Southeast Asia a long time ago 🤣 If I can remember, we don't do alot of hand shaking, certainly not hugs. It's not that we are unfriendly, I think it's just a respect for the other person's space. We do a slight bow of our heads. Some do a deeper bow to elders and people of authority. When I was still in school, we all stood up and gave our teachers a deep bow from our waists when the teacher entered the classroom. I have lived in this country for many decades and got used to handshakes and hugs. I will still hug my family when this is over, but have to think again for my friends. I may have to explain my reluctance. I'm sure they will understand as we are all in the same boat.
