What are the precautions for Russian tourism? What should I pay attention to when traveling to Russia?

Travel notes 1, Moscow and Petersburg are moderately cool in summer, and the weather begins to get cold after September. In most cases, the temperature in winter is about five to fifteen degrees below zero. St. Petersburg is rainy in summer and autumn, so be sure to bring an umbrella; 2. The national currency of Russia is ruble, and other foreign currencies cannot be used directly. For the convenience of shopping and spending abroad, and for the sake of safety, please exchange rubles before leaving the country. Please consult your team leader for details. The tour guide will prepare rubles for you. Please take RMB with you and exchange it at the airport. Due to different living habits, Russian hotels do not provide toiletries and slippers, nor do they provide boiled water for drinking. Tourists must buy bottled water to drink. The room voltage is 220 volts, and the socket is a cylindrical plug, which does not match the domestic flat plug. If you need to charge, please prepare the adapter plug in advance. 4. Dress neatly when entering entertainment places, and it is forbidden to wear slippers, vests, shorts, etc. Please note that smoking in Russia depends on the environment. The general principle is to smoke outdoors. Smoking is not allowed in airports, hotels, shops, museums, railway stations, train boxes and political attractions around Red Square. According to the traditional habits left over from the former Soviet Union, all the goods sold in Russian shops are not bargained. Products that can be bought are: Russian telescope, Russian purple and gold jewelry, Soviet officer watches, dolls, crystal wine sets, amber products, French perfume, Italian leather goods and stockings, black caviar, chocolate, vodka, Russian cigarettes, etc. There are three major mobile operators in Russia, namely мтс, мегаон and билакн. In order to distinguish them easily, they are called by their main colors here: мтс is a red card, мегаон is a green card, and билан is a yellow card. The charges for Russian mobile phone cards will vary from region to region, because most people enter from Moscow. Like China, there is roaming here, so if you apply for a card in Moscow to go to Petersburg, you have to open a roaming discount service, otherwise it may take 10 rubles a minute to answer a phone call. It is suggested that the card office should be located at the airport, the underground passage in the city, the stall at the subway entrance and the card office in the supermarket. To apply for a card in a regular business hall, you need to show a visa on arrival, which is also commonly known as a temporary residence permit. Generally, you don't need to apply for a temporary residence permit if you stay in a place for less than five working days, so visitors can't get a calling card when they go to the business hall. In the stall, the cardholder's information does not need to be stored in the computer, so there is no need to show a temporary residence permit. Note: The method of calling a mobile phone with international roaming function in Russia is: 8 1086+ area code (excluding 0)+ fixed telephone number; The dialing method of mobile phone is: 8 1086+ mobile phone number. It is suggested to contact China by SMS. The method is: +86+ mobile phone number. Internet access in Russia is not very convenient, and wifi in most areas is charged. Most hotels in Moscow have Internet access, but the charges are very expensive, averaging 10-20 USD/day. 80% of Moscow's urban areas are covered with monthly wireless networks, with 500 rubles about 150 RMB, and unlimited Internet access 1 month. You can also choose to use a calling card when surfing the Internet in Moscow. Please consult your local operator for specific tariff details. Power supply and voltage The voltage in Russia is 220V and 50Hz, and the socket has two-phase rounded corners, just like that in Germany. Generally, hotels do not provide adapter plugs. Please bring your own adapter plugs. It is very convenient to buy a GSM power socket adapter before departure.
