This is really hard to say, because it is possible to send something, such as a big customer appreciation meeting. If there are hundreds of thousands, it is not impossible to send a microwave oven. However, it usually doesn't happen when you save money. If so, see if there is a deposit slip or something. If not, ask at the bank. Now you can have no time deposit slip. If you buy wealth management, you can generally withdraw it without loss within three or five days.
