Please help explain the weekly winning business of Shanghai Pudong Development Bank.

To understand the week, we must first know the "seven-day notice deposit". "Seven-day notice deposit" is an irregular deposit, but the bank must be notified seven days in advance before withdrawal, and the interest rate is relatively high. For example, if you deposit a seven-day notice deposit today and want to withdraw it on March 17 next year, you must notify the bank on March 10 tomorrow to enjoy the high interest rate.

However, if the money is suddenly needed urgently, it can be calculated at the current interest rate without seven days' notice.

The week is actually a rolling "seven-day notice deposit". For example, if you deposit a weekly winning deposit today, it is equivalent to deposit a "seven-day notice deposit". If you deposit on the same day, the banking system will automatically notify you on the same day. After seven days, you will automatically withdraw it with interest. Then you will automatically deposit a new "seven-day notice deposit" and automatically notify you on the same day ... so that you can enjoy high interest rates for seven consecutive days. When I need money urgently, I will withdraw it on the spot, that is, the last seven days will be counted as current account, and the first seven days will be counted as notice deposit to keep the income.

Weeks are also different from 1.0 and 2.0. The specific rules are complicated, but the basic principle is what I said above.
