10,000 copies of income is 10,000 yuan a day. For example, if you buy this product for 10,000 yuan, it will cost one yuan and six cents a day. (Then the annualized interest rate of your earnings for that day = 1.6 RMB/10000 RMB * 365 days * 100%=5.84%)

The 7-day annualized rate of return is equal to the money you have saved for 7 days on a regular basis, and the income given to you = principal * rate of return /365 days multiplied by 7 days.
