Read one side:
[1] First, pick a number (0 -7)
I said that each week is thinking out
[2] Take this figure in 2
[3] then add 5
[4] Multiplion 50
[5] If you have passed this year's birthday, add 1754, if you haven't passed, plus 1753
[6] The last step, use this number to subtract your year (Xiyuan)
[7] Now you will have a three-digit number
[8] The first digit is the number of choices you have started (that is, every week you want to go out)
The next number of two digits is your age (please admit)
