What should we pay attention to when traveling in five eastern European countries?

Anti-theft and anti-robbery: European public security is not very good. It is recommended not to show off your wealth, bring too much cash and go to the alley.

Weather: The weather in Europe is changeable, especially in mountainous areas, so we should always pay attention to it.

Tax refund: pay attention to the tax refund requirements of various countries, remember to ask for tax forms when buying things, and check personal information such as passport number and name pinyin.

Mobile phone card: buy a local mobile phone card or network card before going out, so as to surf the Internet at any time and keep in touch with family and friends.

Personal safety: beware of refugees and gypsies, don't trust others, and don't hitchhike.

Bank card: Many banks control the amount of money in consumption abroad. If you want to buy big items, such as brand-name watches, you should contact the bank in advance.

Exchange: It seems that not all EU countries use euros, and Switzerland where I went still uses Swiss francs. If some countries in eastern Europe don't use the euro, remember to change some local currencies, and it's best to check in advance.
