If you want to exchange pounds for pounds in Urumqi, you may have to go through a little trouble. It is recommended to exchange pounds for pounds at a domestic bank.
Domestic banks now have the business of exchanging RMB for foreign currencies. Each person can exchange foreign exchange equivalent to US$50,000 per year with his or her ID card. At the window of a bank savings office, such as Bank of China and China Construction Bank, you can operate it with a bank card. There must be a corresponding amount of RMB in the bank card. If you already have foreign currency in your bank card, such as US dollars, you can exchange it directly for pounds at the bank window. There are restrictions on exchange times, usually before 3pm or 4pm, which is before the domestic foreign exchange market closes, except on holidays and weekends. In comparison, Bank of China's efficiency is relatively high.
But if you are abroad now, it is recommended that it is much more convenient to handle domestic foreign exchange, because handling foreign exchange business abroad generally requires a lot of procedures, and the handling fees are quite high. If conditions permit, you can handle it domestically. Handle it at home
It is also very fast to transfer money abroad from banks. Hurry up and the wire transfer will arrive in one day, so you don't have to worry too much about whether it will be too late for your children to study in the UK in the future.
Hope it helps you
