Who knows Tian Naixin's fortune-telling in Gaotang Tianlou, Shandong Province?

Which eldest brother and elder sister calculated hexagrams in Gaotang Tianlou, and the calculation is accurate or not. Think about what to break? How much is it once? I'm from Liaocheng, and the calculation is very accurate, but the charge is very high, which costs thousands of dollars. Where is the specific location of Gaotangtian Building? I'm waiting for the answer online.
