Visitors take selfies at the Benaki Museum of Greek Culture, one of the most significant museums in Greece, in Athens, Greece, on Jan. 17, 2018. A few years ago museum visitors who dare to take photographs of artwork would get scolded by security personnel in most cases. Nowadays, people are encouraged to use their mobile phones to shoot selfies in front of masterpieces. (Xinhua/Marios Lolos)
