It is best to run an online banking and fund business, so that you can run all over the country, and you can buy it as long as you can get online, without being restricted by the counter. If you handle it at the counter, you can only buy it locally. If you can't buy it in other places, you can transfer it. The salesman who handles the funds for the bank will help you. You bought it in Shanghai now, so you have to redeem it in Shanghai. You can't exchange it locally when you go home. If you want to continue buying, just change your fund trading account in a bank in another city.
