How to find the lower dan tian ?    (like really finding the real location and knowing you found it)

i seen about  some place you just let your awareness "sink"  by doing meditation and by that it will automatically lower itself down  until when it reaches the lower dan tian level it will "suck it up"  or something like that 

I have an inconsistent meditation practice and thats maybe why i dont get any  "achievements"   to now  but i did start to meditate 12 years ago  and did a few meditation retreats  .......   and  it doesnt seem that it should take years to just find (if someone is looking for it)  and if soo would be a shame to spend another 12 years just to find it  ......     so maybe i didnt get things right and its not just to meditate and you will find it ?

what are some ways to find it ?  how to find it ?    any detail someone wants to add on the topic is welcomed
