1. Studying in the UK is not allowed to bring too much cash. Generally, you can carry about 700 Jin with you. If you bring thousands of pounds, it will be confiscated when you re-enter. It will delay you for a while.
Drawing a draft is the best choice. Go to England and open a personal account in any bank in England, and then I will deposit the draft in my English account with my passport. After 7 working days, the money will be remitted to your account without any formalities.
3. For handling in China Bank, only China Bank can, and the foreign exchange stock is relatively large, so if the amount of foreign exchange applied for is large, it is still China Bank. Nothing is different than too much. It is more convenient to go through a set of procedures in China Bank.
4. It's you.
I hope the answer will help you!
