You should also visit the Romanian Lipovans. They also preserved traditions and language very well and mostly live in the Danube delta. One of the greatest Romanian sportsman was the Lipovan Ivan Patsaikin, multiple world and Olympic champ at kayak canoe, very much loved in Romania. The old man just reminded me that in Transylvanian villages there is also the habit to just place a brush in the door, when not home, and no one will go in. lol Also the Ro Orthodox church baptizes by complete submerge 3 times of the babies, but the cross is done like in other Orthodox churches, by 3 fingers, signifying the holly trinity: the Father, the Son and the Holly Spirit, while the 2 fingers in the palm signify the duality of Christ: divine and human.
