I am going to Ulan-Ude, Russia. Who can tell me some basic information there?

I haven't been to Ulan-Ude, Russia, but I have been to Moscow and St. Petersburg. I think the basic situation is similar. The living standard in Russia as a whole is not very high, and the price is much lower than that in China. I suggest that you bring US dollars, which can be exchanged by all banks. Some shops even accept RMB, but compared with US dollars, using RMB is still a bit disadvantageous! The public security situation is not very good, and it can be said that it is relatively poor. I suggest that you don't go out casually after you go. Both the mafia and the police are very dark, but it is very simple to handle the police. Generally, it takes 4 rubles, which is equivalent to RMB, that is, 1 yuan money! Then, when flying in Russia, be careful not to carry valuables, such as jewelry and money, in the checked baggage, or it will be easily lost! The environment is still good, the whole of Russia is green vegetation, basically not destroyed! !
