Can you use renminbi in Taiwan directly?

No, you cannot use renminbi in Taiwan directly. The official currency of Taiwan is the New Taiwan dollar (TWD). While renminbi (RMB) is the official currency of mainland China, it is not widely accepted in Taiwan. If you wish to make purchases or payments in Taiwan, it is recommended that you exchange your renminbi into New Taiwan dollars. You can do this at local banks or currency exchange services in Taiwan.
