How to choose a lottery for a family of three on their birthday?

A lottery family of three has a combination of split year and birthday month.

1, split year: Take 1992 as an example, it can be split into three numbers: 19, 09, 02 is a red ball. Of course, there are special circumstances. 1977, 1988, 1999 in these special years, one of the repeated single digits can be taken out to buy a blue ball, and the other is still counted as the number in the red ball.

2. Birthday month combination: Birthday consists of solar calendar and lunar calendar. For example, March 20 of the lunar calendar in a certain year is April 22 of the solar calendar. All these numbers less than 3 1 can be positioned as alternative red balls. In a group of lunar months, you can get up to 4 numbers, and if there is duplication, you can also get 3 numbers. 3. Handling of special numbers: Because there are numbers in the two-color ball that are not in the months of 32 and 33. Then choose these two numbers as backup numbers in case you need to make up the position. If the birthday of June 10 in the Gregorian calendar is 1992, the tenth day of the fifth lunar month. The numbers are 19, 09, 02, 06, 10, 05 and 10. Six red numbered balls are determined as 19, 09, 02, 06, 10, 05, 1 blue numbered balls are determined as 10.
