20 best 3d number

Hi sifu, i m new here, may i know how you get the best 20 3D number from?
is it from past result? i still don't understand and what is the trend we should follow?

Hi, normally i buy damacai counter, 10s

I have strike 3d numbers quite easily... every 2 draws I strike. I feel this is the best game to play.... Low prize money but frequent strikes. I will catch the 100k jackpot soon... My prediction for 3d for 9/8/14 869, 137,246.....
