Thailand uses Thai baht. You can change it at home before you go. Generally speaking, banks can exchange foreign currency anywhere. Just bring your ID card. Singapore and Malaysia like RMB more and more now, but people are reluctant to accept dollars. Haha, the RMB is strong. I remember I didn't stay there long. I can change with the tour guide. Don't feel uneconomical. You haven't changed much, but you may be short of a few dollars. The most important thing is that you can exchange it with the tour guide if you haven't used it up. Calculated, it is more cost-effective than replacing it in China and selling it back to the bank. And save so many things.
Thai people don't earn much, and their income mainly depends on tips. . . I'm not talking about tipping the tour guide. . . Get up every day and put twenty baht or five RMB at the bedside. The waiter may help you clean up more carefully. Just put it in a room alone. Of course, you can put more money.
Generally speaking, the law and order in these three countries is still good. Don't think that yellow shirts and red shirts in Thailand are terrible. I met them once. This is like a family carnival. It is very interesting to sit or stand and shout slogans. Besides, all the places you go to are tourist attractions, and people are playing with the government, not you.
Hope to adopt
