Why do you hang so many clocks on the hotel wall?

On the surface, it is for foreign guests to see the time. Now it is the information age, and the clock on the mobile phone generally has the function of multi-time. Nowadays, almost everyone can't leave their mobile phones at home, not to mention some people are stupid enough to go abroad without their mobile phones (if a foreign guest says he forgot to bring his mobile phone, it is estimated that there will be a "smile service" soon), so the world clock in the hotel is actually a feng shui decoration, the number of wall clocks and which area to choose. If you look carefully, the clocks in some hotels are not necessarily consistent with the world time (including Beijing time) of mobile phones. The clocks on the walls of some hotels are all Beijing time, and even the clocks in some hotels are running except Beijing time. Everything in London has stopped and there is no electricity. They think that the accuracy of these clocks is not the most important thing.
