There is no problem in shopping with UnionPay cards in major tourist cities such as Rome and Barcelona. If you want to eat and live, it depends on whether there is a UnionPay channel.
2. The dual-currency card of the landlord depends on whether it is a euro card. If it is a dollar card, you need to purchase foreign exchange in dollars to buy euros, and there is an exchange procedure in the middle.
3. Domestic banks exchange foreign exchange according to the foreign exchange quotation of the day. It doesn't make much difference which bank to go to. Go to the Bank of China.
If the euro is not spent, you can exchange it in the bank when you go back, but now the exchange rate of the euro has been falling. If it's less, you won't lose much if you change it into RMB, and if it's more, the loss will be even greater. It is suggested that the landlord use credit cards more.
5. The landlord can bring a visa credit card, and basically you can swipe your card for accommodation, catering and shopping. The UnionPay savings card can be withdrawn at ATMs marked UnionPay in Societe Generale, LCL Bank, French Agricultural Credit (CA) Bank, Swiss Six, Italy setefi and German Savings Bank.
6. Regarding cash, it is suggested that the landlord exchange foreign exchange according to the number of days of travel × 50 euros per day to avoid excessive exchange, and now that the exchange rate of the euro has dropped, it will be much more cost-effective to swipe the card.
