When traveling to Moscow, are there any customs regulations on how much cash I can carry? Another question is, what channels are there to exchange rubles in Moscow?

Like many tourist cities, rubles can be exchanged in the center of Moscow and in several places where tourists are concentrated. At the same time, banks near scenic spots can also exchange cash, and there are also some hotels. As long as you see the mark exchange, it means they can also exchange. Some friends also told me that before going to Moscow, it is most cost-effective to first exchange RMB into US dollars in China, and then exchange US dollars for rubles in Moscow
