The combination of the award numbers for this period is perfect: red ball 01, 03, 19, 20, 24, 25, blue ball 07. The brightest feature is the appearance of a double chain, which is visible in the current number, with the simultaneous opening of the 19-20 in sector centre and the 24-25 in region large. The number is a four-chitt ratio of two to two, with an odd number of blueball 07, and the total number of oddballs is the best; the size of the area is even, with two small, two medium and two large, no break zone blanks, and the exit is mild and non-impressive。
